You can put this solution on YOUR website!
Equal degree, numerator and denominator; horizontal asymptote y=1.

f%28x%29=%28%28x%2B2%29%28x-2%29%29%2F%28%28x-5%29%28x%2B3%29%29

Zeros for x=-2 and x=2.
Vertical asymptotes x=-3 and x=5.

You can figure how the branches go as positive or negative in each interval.
You do that!
