Question

4. Let f(x)=-2x+7 and g(x)=-6x+3. Find f×g and state its domain

A. 12x^2-48x+21;all real numbers
B. -14x^2+36x-18;all real numbers except x=7
C. -14x^2+36x-18;all real numbers
D. 12x^2-48x+21;all real numbers except x=1

Answer 1

the answer is A ...

Answer 2

I hope this helps you

(f.g) (x)=(-2x+7)(-6x+3 )

(f.g)(x)=12x^2-6x-42x+21

(f.g)(x)=12x^2-48x+21
