Question 474616: Which of the following is a function whose domain and range are all nonzero real numbers?
A) f(x) = 6/2x + 3
B) f(x) = x - 1/x + 5
C) f(x) = 4x - 7/x
D) f(x) = x/2x - 8
E) None of these
You can put this solution on YOUR website!
D) f(x) = x/2x - 8 is a function whose domain and range are all nonzero real numbers
; so, whatever you take for value of it will cancel each other in nominator and denominator
