Question

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

−30
0
10
12

Answer 1

so u see
g(-1) = -1 + 3
g(-1) = 2
now u need to find f(g(x))...
and g(-1) = 2
so f(2) = 5*2 - 10 = 0

Answer 2

So basically you just fill it in and solve it then use the first equation to solve the second one?

Answer 3

see it says f(g(x)) at x = -1
so first u need to calculate g(x) at x = -1
