Question

if (fx) = x^2 + 1 and g(x) = 2x, find [f*g](x) how do I solve this??

Answer 1

\(\bf f(x)= x^2 + 1 \qquad g(x) = 2x
\\ \quad \\\
[f\cdot g](x)\implies f(x)\cdot g(x)\implies (x^2+1)\cdot (2x)\implies ?\)

Answer 2

Would I just factor it??

Answer 3

well, is just a multiplication

Answer 4

2x(x^2+1)?

Answer 5

yes

Answer 6

not one of the answer choices :// 2x^2+1 is one of them
