Question

F(x)= x+3
h(x)= x^2+4

Find (f•h)(x)

Answer 1

x³+3x²+4x+12

Explanation:

you are going to write both equations and distribute. if there are like terms, combine them and then put it order.

(x + 3) × (x² + 4)

x³ + 4x + 3x² + 12

when putting in order, you want the highest power to the left and then the lowest power to the right.

so

x³+3x²+4x+12
