Question 112184


{{{f(x)=(6)/(x-8)}}} 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+8}}}Add 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
