If f(x) =3x2 and g(x)=4x3+1, what the degree of (f•g)(x)?

2
3
5
6

f(x) = 3x²

g(x) = 4x³ + 1

f(g(x)) = 3.(4x³ + 1)²

As we know

(a + b)² = a² + 2.a.b + b²

So,

(4x³ + 1) = (4x³)² + 2.4x³.1 + 1² =

f(g(x)) = 3.()

The degree is the maximum exponent, so, 6.

yo answer should be 6 if im not mistaken
