g(x)= 8/109x
would the correct answer be
a) {xIx is a real number and x ==/== 10/9?
b){xIxis a real number and x equals lesser or equal to >_ 10/9
c){xIx is a real number and x =/= 0
d){xIx is a real number and x =/= 8
my answer is c is this correct?

Math 
jim,
No, c is not correct.
In each of the other cases, what happens when x is the number given:
a) 8/(1090/9)
b) x < 10/9, say 1/9 > 8/(109/9)
d) 8/(1072)
One of these three is undefined. Which?

On what grounds do you choose d?
