Exercise 5 Page 541

Make a table of values to find points from each graph.

Graph:

Transformations: vertical stretch by a factor of $2$ and vertical translation $2$ units down.

Practice makes perfect

We want to graph functions

f

and

g

and describe transformations from the graph of

f

to the graph of

g .

We will start by rewriting the function

g .

g (x) = 2 x - 2 \Leftrightarrow g (x) = 2 f (x) - 2

First, let's use a table of values to find points on the graph of

f (x) = x .

$x$	$f (x)$
$- 2$	$- 2$
$0$	$0$
$3$	$3$
