2-151.

Find the $x$ - and $y$ -intercepts for the following parabolas.

$y = (x + 12)^2 − 144$
Hint (a):
To find the $x$ -intercepts, substitute $0$ for $y$ , and solve for $x$ .
To find the $y$ -intercepts, substitute $0$ for $x$ , and solve for $y$ .
Answer (a):
$x$ -intercepts: $(0,0),(−24,0)$
$y$ -intercept: $(0,0)$

$y = (x − 8)^2 − 4$
Hint (b):
Refer to part (a).
