(fg)(x)= x³ - 7x² - 9x + 8
domain is (-∞,∞)
Given: f(x)= x-8, g(x)= x² +1x - 1
To find (fg)(x) we multiply f(x) and g(x)
(fg)(x) = f(x) * g(x)
(fg)(x)= (x-8) (x²+x-1)
(fg)(x)= x³ + x² - x - 8x² - 8x +8
(fg)(x)= x³ - 7x² - 9x + 8
we know, domain for all cubic function is set of all real numbers
domain is (-∞,∞)

Answer:
Hello there, I love answering these questions!
Step-by-step explanation: turn 3/4 into 6/8 = 3x2/4x2 then subtract. 6/8 - 3/8 = 3/8
Hope this helped you! Have a wonderful day!
