Step-by-step explanation:
f(x) = 5x + 2
g(x) = x2 – 1
Think of it like a sandwich:
first solve what g(x) will be equal to when x = 3 (this is what's given in "f(g(3))" )and then plug in the answer into the equation of f(x) to find the final answer
the resulting equation will look like this:
f(g(3)) = 5[(3)2 - 1] + 2
just solve using PEMDAS
= 5[6-1] +2
=5[5] +2
=10+2
=12
Answer:
f(g(3)) = 12
