Question

Find the domains of the following functions: y= 1/x-2

Answer 1

x is all real numbers, where x ≠ 2

Explanation:

Domain is the input of x-values that can work in a function. Since we can't have 0 in the denominator (undef error), we have to exclude x = 2, as it will make the denominator 0. However, every other x-value works.
