A function assigns the values. The (f·g)(x) equals 5x³ + 5 + 5x²+15x.
What is a Function?
A function assigns the value of each element of one set to the other specific element of another set.
Given the value of the functions f(x)=5x³ and g(x)=x+1. Therefore, the value of (f·g)(x) is,
(f · g)(x) = f(g(x))
= 5(x+1)³
= 5(x³+1+3x²+3x)
= 5x³ + 5 + 5x²+15x
Hence, the (f·g)(x) equals 5x³ + 5 + 5x²+15x.
