Question

F(x)=x-4 g(x)=-5x-3 find g(f(1))

Answer 1

g(f(1)) = 12

Explanation:

Given the functions f(x) = x-4 and g(x) = -5x-3 you want the value of g(f(1)).

Evaluation

Put the value of the variable where the variable is and do the arithmetic.

g(f(1)) = g(1 -4) = g(-3) = -5(-3) -3 = 15 -3

g(f(1)) = 12
