Hint (a):
Factor first.
Hint (a):
This function has a vertical asymptote at $x = -1$ . How does that affect range?

$y = \frac { x ^ { 2 } - x - 6 } { x + 2 }$
Hint (b):
Factor first.
Hint (b):
This function has a hole at $x = −2$ . It's end behavior is $y = x-3$ , which can help you find the $y$ -value of the hole.
