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

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.

is only a line? i think so

a: 1/6, j: 1/4
