Question

Let f(x) = -4x - 2 and g(x) = 5x - 6. Find f×g and state its domain

Answer 1

see explanation

Explanation:

f(x) × g(x)

= (4x - 2)(5x - 6) ← expand factors

= 20x² - 24x - 10x + 12 ← collect like terms

= 20x² - 34x + 12

This is a polynomial of degree 2 and is defined for all real values of x

domain : x ∈ R
