Given that f(x)= 2/x^2
and g(x) = 13/x^2
What is the domain of the functions fand g?
a. only positive integers
b. All non zero real numbers.
c. only negative integers
d. All real numbers including zero​

Answer:

b.

Step-by-step explanation:

You have fractions.  Fractions don't output if the denominator is 0 because you cannot divide by 0.

So 2/x^2 and 13/x^2 have issues when x=0 because it leads to 2/0 and 13/0 respectively.

The domain is all real numbers except x=0.

An equivalent way of saying that is all non-zero real numbers.
