Answer:
(f о g)(0) = 24
Step-by-step explanation:
f(x) = -5x - 1
g(x) = x² - 5
When you see (f о g)(#), they want you to plug the function g(x) into the function f(x).
First find g(0).
g(0) = (0)² - 5
g(0) = 0 - 5
g(0) = -5
Now plug g(0) = -5 into f(x) by replacing all x's with -5.
(f о g)(0) = -5(-5) - 1
Multiply.
(f о g)(0) = 25 - 1
Subtract.
(f о g)(0) = 24
