Question

Evaluate: f(x) = f(g(3)), where
f(x)= 3x-2 and g(x)= x^2-4

Answer 1

13

Explanation:

g(3)=3^2-4

g(3)=9-4

g(3)=5

f(x)=f(5)

f(5)=3(5)-2

f(5)=15-2

f(5)=13

Answer 2

Hello from MrBillDoesMath!

Answer: 13

Discussion:

Evaluate f(g(3)).

g(3) = 3^2 -4 = 5 so

f(g(3)) = f(5) = 3*5-2 = 15 -2 = 13

Thank you,
