# How do you find the range of b(x)=-x^2 for the domain (-2,0,3,8)?

R{0,-4,-9,-64}

#### Explanation:

Plug in each x into the function.
The value of b(x) will be in your range.

$b \left(- 2\right) = - 4$
$b \left(0\right) = 0$
$b \left(3\right) = - 9$
$b \left(8\right) = - 64$

Therefore the range is {-4,0,-9,-64}, rearranged to {0,-4,-9,-64}.
