I'm assuming the function is
Since you cannot divide by zero, this means the denominator cannot be zero.
If it were zero, then --->
In reverse, this means that if then the denominator is zero.
-------------------------------------------------------
Because causes the denominator to be zero, we have to kick this number out of the domain. Any other number works.
So the domain is the set of real numbers x BUT x cannot equal 13.
In interval notation, the domain is \cup\left(13,\infty\right))
