Let f(x) = -4x - 2 and g(x) = 5x - 6. Find f⋅g and state its domain.
Accepted Solution
A:
Answer:-20x^2 +14x+12The domain of f*g is all real numbersStep-by-step explanation: f(x) = -4x - 2 g(x) = 5x - 6.f*g = (-4x-2) * (5x-6) FOILfirst -4x*5x = -20x^2outer -4x*-6 = 24xinner -2*5x = -10xlast -2 *-6 = 12Add them together-20x^2 +24x-10x+12 = -20x^2 +14x+12The domain of f is all real numbers, the domain of g is all real numbersThe domain of f*g is all real numbers
