Exercise 16 Page 8

The given function is linear, so its parent function is $f (x) = x .$ We will start by graphing both functions in one coordinate plan. Then we will compare them to describe the transformation.

Graphing the Functions

To graph both of the functions, we will use their slopes and $y -$ intercepts.

Function	Slope-intercept form	Slope	$y -$ intercept
$y = x$	$y = 1 x + 0$	$1$	$0$
$y = - x$	$y = - 1 x + 0$	$- 1$	$0$
