You can put this solution on YOUR website!
Division by zero is the issue with these and excludes values of x since it's undefined.
y=-1%2Fx
x%3C%3E0
.
.
y=3%2F%28x%2B5%29
x%2B5%3C%3E0
x%3C%3E-5
.

You can do the last one the same way.
Solve for when the denominator equals zero.
Then exclude that value of x.
