    Determining The Equation from a Rational Graph

    Determining The Equation from a Rational Graph-untitled.png
    I have no idea how to solve that question,
    This is what I have so far:

    f(x)= (x-1)(x-5) / (x-3)(x-5) but this yields a different graph..

    Hmmmmm...Always check for asymptotes and intercepts. What is the y intercept of the function you wrote? What is the y intercept of the function in the graph?

    Finally, how many factors of x - 3 can you have?

    Re: Determining The Equation from a Rational Graph

    Well, the HA is y=0, and we can have more than 1 factor of (x-3), (I did not think about that). So our possible equation is : f(x) = (x-1)/(x-3)^2 x!= 3 and 5 . Thank you!!!
