Question 801636: y^3(y-4) / y^2(y-4)
It says for each rational function, find all numbers that aren't in the domain. Then give the domain in set builder. I'm having troubles seeing as I lost the sheet with the notes to this section

You can put this solution on YOUR website! y^3(y-4) / y^2(y-4)
It says for each rational function, find all numbers that aren't in the domain.
---------
The denominator cannot be zero::
Solve y^2(y-4) = 0
y = 0 or y = 4
-----------------
Domain: All Real Numbers except y = 0 and y = 4
{y | -oo< y < 0, 0< y < 4, 4< y <+oo}
