(fg)(x)= x³ – 7x² – 9x + 8domain is (-∞,∞)Given: f(x)= x-8, g(x)= x² +1x – 1To 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 + 8we know, domain for all cubic function is set of all real numbersdomain is (-∞,∞)Know more about “functions” here: https://brainly.com/question/12431044#SPJ4
