f%28x%29=%286%29%2F%28x-8%29 Start with the given function


x-8=0 Set the denominator equal to zero. Remember, dividing by 0 is undefined. So if we find values of x that make the denominator zero, then we must exclude them from the domain.



x=0%2B8Add 8 to both sides


x=8 Combine like terms on the right side





Since x=8 makes the denominator equal to zero, this means we must exclude x=8 from our domain
