Let f(x) = -4x - 2 and g(x) = 5x - 6. Find f*g and state its domain.
elixir [45]

Answer:  The answer is (c) -20x^2+14x-12;\textup{ all real numbers.}

Step-by-step explanation:  Given that there are two functions f and g, defined by

f(x)=-4x-2,\\\\g(x)=5x-6.

We are to find f*g and also its domain.

(f*g)(x)\\\\=f(x)g(x)\\\\=(-4x-2)(5x-6)\\\\=-20x^2+24x-10x-12\\\\--20x^2+14x-12.

Also, its domain will be all real numbers, since the function f*g is defined at all 'x' in real numbers.

Thus, the correct option is

-20x^2+14x-12.
