Question 249111
f(x)=8/x, g(x)=9x^2-5
---
Notice: x cannot be 0 because of 8/x, so g(x) cannot be -5.
----------------------------------------------------------------
f*g(x) = f(x)*g(x) = (8/x)(9x^2-5) = 72x -(40/x)


The answers are

A) {x[x is a real number and x not equal to -9
b) {x[x is a real number and x not equal to 5
c) {x[x is a real number
d) {x[x is a real number and x not equal to 0
