Dilation Dilation is also a transformation which causes the curve stretches (expands) or compresses (contracts) Multiplying a function by a positive constant vertically stretches or compresses its graph; A horizontal translation 60 is a rigid transformation that shifts a graph left or right relative to the original graph This occurs when we add or subtract constants from the \(x\)coordinate before the function is applied For example, consider the functions defined by \(g(x)=(x3)^{2}\) and \(h(x)=(x−3)^{2}\) and create the following tablesHave a play with this 2D transformation app Matrices can also transform from 3D to 2D (very useful for computer graphics), do 3D transformations and much much more The Mathematics For each x,y point that makes up the shape we do this matrix multiplication

That is, the graph moves away from xaxis or towards xaxisA function transformation takes whatever is the basic function f (x) and then "transforms" it (or "translates" it), which is a fancy way of saying that you change the formula a bit and thereby move the graph around For instance, the graph for y = x 2 3 looks like thisProperties of Linear Transformations There are a few notable properties of linear transformation that are especially useful They are the following L(0) = 0L(u v) = L(u) L(v)Notice that in the first property, the 0's on the left and right hand side are differentThe left hand 0 is the zero vector in R m and the right hand 0 is the zero vector in R n

Reflection Mirror image of a function A transformation takes a basic function and changes it slightly with predetermined methods This change will cause the graph of the function to move, shift, or stretch, depending on the type of transformation The four main types of transformations are translations, reflections, rotations, and scalingAnswer choices a reflection across the line x = 4 a reflection across the line y = 4 a translation shifting f (x) 4 units to the left a translation shifting f (x) 4 units to the rightApplying transformations step by step 9 • The order in which transformations are applied will determine the "nal equation 1 Translation of 3 units to the right y=(x−3)2 4 Translation of 4 units up 2 Dilation by 2 from the x axis 3 Re!ection about x
This base parabola has the formula y=x^2, and represents what a parabola looks like without any transformations being applied to it The table of values for a base parabola look like this The reason this small equation forms a parabola, is because it still has the degree 2, something discussed in the previous lesson Shift to the right by 2 units, vertical translation upwards by 3 units The parent function of the graph is y=x^2 Using the general equation y=af(kxd)c, Where if a > 1=vertical stretch, 0< a < 1= vertical compression f(x)=reflection in the xaxis f(x)=reflection in the yaxis 0 < k < 1= horizontal stretch, k > 1= horizontal compression d=horizontal shift to the right d=180 seconds Q Which transformation maps the graph of f (x) = x 2 to the graph of g (x) = (x 4)2?

Describe the Transformation y=x^2 The parent function is the simplest form of the type of function given For a better explanation, assume that is and is The transformation being described is from to The horizontal shift depends on the value ofThen T is a linear transformation, to be called the zero transformation 2 Let V be a vector space Define T V → V as T(v) = v for all v ∈ V Then T is a linear transformation, to be called the identity transformation of V 611 Properties of linear transformations Theorem 612 Let V and W be two vector spaces Suppose T V →Once students understand the rules which they have to apply for reflection transformation, they can easily make reflection transformation of a figure For example, if we are going to make reflection transformation of the point (2,3) about xaxis, after transformation, the point would be
Answer and Explanation 1 We are given the function y = x2 y = x 2 The graph of this function changes to y = −x2 y = − x 2 The graph transformation that happens in this function isTransformations "before" the original function We could also make simple algebraic adjustments to f(x) before the function f gets a chance to do its job For example, f(xd)isthefunctionwhere you first add d to a number x, and only after that do you feed a number into the function f The chart below is similar to the chart on page 68SECTION 13 Transformations of Graphs MATH 1330 Precalculus 87 Looking for a Pattern – When Does the Order of Transformations Matter?
Function Transformations Just like Transformations in Geometry, we can move and resize the graphs of functions Let us start with a function, in this case it is f(x) = x 2, but it could be anything f(x) = x 2 Here are some simple things we can do to move or scale it on the graphA vertical stretch or compression a > 0, the parabola opens up and there is a minimum value a< 0, the parabola opens down and there is a maximum value (may also be referred to as a reflection in the xaxis) 1 See below The first thing you need to find is the axis of symmetry by using b/2a after you find that, use it to find the vertex of x^28 In this case x should equal 0 so y=0^28 giving just 8 the yintercept is 8 as c=8 the graph should look like this graph{x^28 115, 85, 084, 1084} it is a parabola
It's like f (x)=x3 except the 3 is inside absolute value brackets The only difference is that you will take the absolute value of the number you plug into x Remember that x just represents an unknown number To find f (x) (you can think of f (x) as being y), you need to plug a number into x f (x)=x3 x=2"vertical transformations" a and k affect only the y values) Note When using the mapping rule to graph functions using transformations you should be able to graph the parent function and list the "main" points Example 3 Use transformations to graph the following functions a) h(x) = −3 (x 5)2 – 4 b) g(x) = 2 cos (−x 90°) 8We need an m x n matrix A to allow a linear transformation from Rn to Rm through Ax = b In the example, T R2 > R2 Hence, a 2 x 2 matrix is needed If we just used a 1 x 2 matrix A = 1 2, the transformation Ax would give us vectors in R1
We have to graph the function using the rule for transformation Let us suppose the parent function is Below, is the graph of the parent function (fig 1) When we add some constant 'c' in the function then the graph of the parent function shifts upward by 'c' units Hence, when we add 2 then the parent function will get shifted upward by 2 unitsThis video explains how to determine the equation of an expoential function with a horizontal reflection and a vertical shifthttp//mathispower4ucomTransformations and Matrices A matrix can do geometric transformations!
