f(x)=v^2+13/v^24v32
Find all numbers that are not in the domain of the function. Then give the domain in set notation.

set denominator equal to 0 and solve for x which would make the equation undefined
v^24v32=0
(v8)(v+4)=0
v=8, v=4
x is not equal to 8 or 4 
The denominator cannot be zero, so find the roots of the denominator.
(v8)*(v+4)=0
so v cannot be 8, or 4
