Question

Given that f(x) = 5x − 10 and g(x) = x + 3, solve for f(g(x)) when x = −1. (1 point)

−30

10

12

Answer 1

0

Explanation:

Given: f(x) = 5x − 10 and g(x) = x + 3

f(g(x)) = 5(x+3) -10

f(g(x)) = 5x + 15 -10

f(g(x)) = 5x + 5

f(g(-1)) = 5(-1) + 5 (plugging x = -1)

f(g(-1)) = -5 + 5

f(g(-1)) = 0
