Expert Answer:

Dear student
Please raise only one question in a query
(i) A real function is one whose domain and range are either set of Real numbers or any of its subsets.
(ii)  f: -> R
this statement is incomplete it must be f:R--->R which means f is a function from set of real numbers  R to R
(iii) f(x)/g(x)  g(x) not equal to 0 because division by zero i snot defined
