Assume the function has only one x-intercept at the origin, and the point marked on the graph is located at (6,-3/5). The asymptotes are x=-4 and x=5. give the formula as a reduced rational function.

Answer 1

y = ax / (x+4)(x-5)
Now just plug in your point to find a:
-3/5 = a*6 / 10*1
a = -1
y = -x/((x+4)(x-5))
