Answer:
109
Step-by-step explanation:
9 + |-78| - (-22)
Apply the absolute value which states |-x| = x.
9 + 78 - (-22)
Apply the rule that states x - (-y) = x + y.
9 + 78 + 22
Add 9 and 78.
87 + 22
Add 87 and 22.
109.

The range of the function y = -x² - 3x when the domain is {-5,0,2} is:
{-10, 0}.
<h3>What is the range of a function?</h3>
The range of a function is the set that contains the output values for the given domain of the function.
In this problem, the domain is:
{-5,0,2}.
Hence the output values are:
- -(-5)² - 3(-5) = -25 + 15 = -10.
- -(2)² - 3(2) = -4 + -6 = -10.
Hence the range is:
{-10, 0}.
-10 repeats, but goes only once on the range.
