Question

Given: f(x)=x^(2)-3 and g(x)=x+1 the composite function g*f is

Answer 1

Answer:

x³ + x² - 3x - 3

Step-by-step explanation:

I'm assuming g*f means g times f,  so you want to multiply the two functions together.  

(x² - 3)(x + 1)                 Since the product is 2 binomials, use FOIL

                      =  x²(x) + x²(1) - 3(x) - 3(1)

which simplifies to

x³ + x² - 3x - 3
