How do I go about solving this equation

Question

f(x) = x + 3 g(x) = 2x ^ 2 - 4 Find f* g)(x) .

Answer 1

Hi,

As it is given that f(x) = x + 3;

g(x) = 2x^2 - 4

find (f*g) = ?

solution: multiply both the function and then rearrange them to get the final answer

f*g = 2x^3 -4x +6x^2-12

= 2x^3 + 6x^2 -4x -12

Thank you

Please rate my answer and ask me if you have further doubt.

Answer 2

This is multiplication. It would be (x+3)(2x²-4)

Can you FOIL it from here?
