Question

If given f(x)=x-7 and g(x)= x^2 how would you find g(f(4))?

Answer 1

9

Explanation:

First evaluate f(4) then substitute the value obtained into g(x)

f(4) = 4 - 7 = - 3

g(- 3) = (- 3)² = 9

⇒g(f(4)) = 9

Answer 2

g(f(4)))=9

Explanation:

f(x)x-7

f(4)=4-7=-3

g(f(4)))=(x-7)^2>3^2=9

g(f(4)))=9
