## Homework Statement

## Homework Equations

The denominator of a function cannot equal 0. Both the numerator and denominator also cannot = 0 simultaneously.

## The Attempt at a Solution

For the first problem, the denominator and the numerator are 0 when x =0. Hence, I excluded it from the domain. Similarly, for the second problem, the denominator is 0 when x = -8. It is also excluded from the domain. Am I missing something?
