Question

Given the functions, f ( x ) = x - 8 and g ( x ) = x2 x - 1, perform the indicated operation. when applicable, state the domain restriction. ( fg )( x )

Acacia · Answer

(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  (-∞,∞)        Know more about ' functions ' here: https://brainly.com/question/12431044  #SPJ4
