Question

Plot the points of the pre-image and graph the pre-image.

Answer 1

Given:

The Point is:

`\begin{gathered} W(2,2) \\ \\ X(2,0) \\ \\ Y(0,1) \\ \\ Z(1,2) \end{gathered}`

The scale factor is 3.

Find-:

Create the point W'X'Y'Z'

Explanation:-

The scale factor is 3.

So the point is:

`\begin{gathered} W^(\prime)=3W \\ \\ W^(\prime)=3(2,2) \\ \\ W^(\prime)=(6,6) \end{gathered}`

Point X' is:

`\begin{gathered} X^(\prime)=3X \\ \\ X^(\prime)=3(2,0) \\ \\ X^(\prime)=(6,0) \end{gathered}`

The point Y' is:

`\begin{gathered} Y^(\prime)=3Y \\ \\ Y^(\prime)=3(0,1) \\ \\ Y^(\prime)=(0,3) \end{gathered}`

The point Z' is:

`\begin{gathered} Z^(\prime)=3Z \\ \\ Z^(\prime)=3(1,2) \\ \\ Z^(\prime)=(3,6) \end{gathered}`

The graph of WXYZ.

The graph of W'X'Y'Z'
