rational functions... PLEASE HELPPPPP
posted by luke .
A rational function that passes through (0,0) and (4, 8/7) has the x-axis as a horiztonal asympotote. It also has 2 vertical asymptotes x=3, x=-3.
I understand that to set it up, it is
y= ax+b / (x+3)(x-3).
I don't understand how to solve for a and b.
