Question

What value of x is not in the domain of f(x)=12/x

A.6
B.0
C.-3

Answer 1

B, 0

Explanation:

if you plug in 0 into the function, you will get f(x)=12/0. This will result in an undefined output, so there will be a hole where x is equal to 0. Therefore, 0 is not in the domain of the function.
