Answer:
f(-7) = 60
Explanation:
In this problem, we are asked to find the output of the function f(x) when x = -7.
First, substitute -7 in for x.
f(x) = -9x - 3
f(-7) = -9(-7) - 3
Then, simplify the right side of the equation. Remember that a negative times a negative becomes positive.
f(-7) = 63 - 3
f(-7) = 60
