Question

If f(x)=x^2+3x and g(x)=5x-2, then f(g(3))=
A.13 B.28 C.88 D.208 E.340

Answer 1

------------------------------------------------------
Equation Given:
------------------------------------------------------
g(x) = 5x - 2

------------------------------------------------------
When x = 3:
------------------------------------------------------
g(3) = 5(3) - 2
g(3) = 15 - 2
g(3) = 13

------------------------------------------------------
Substitute g(3) = 13 into f(x):
------------------------------------------------------
f(g(3)) = (13)² + 3(13)
f(g(3)) = 208

------------------------------------------------------
Answer: f(g(3)) = 208 (Answer D)
