Find f(g(-2)) if f(x)4x plus 5 and G(x)22-1?

Answer 1

g(x) = 22 - 1 = 21 so g(2) = 21then f(g(-2)) = f(21) = 4*21 + 5 = 89.

Answer 2

To find f(g(-2)), we need to substitute -2 into g(x) first. Thus, g(-2) = 22 - 1 = 21. Now, we can substitute g(-2) = 21 into f(x). So, f(g(-2)) = f(21) = 4(21) + 5 = 89. Therefore, f(g(-2)) is equal to 89.
