    Finding the equation of a graph!

    Find the equation of the graph shown (see attachment file).

    The graph I drew is not to scale and I drew it myself because my scanner is broken. Any help regarding this problem will be appreciated! Please show complete working out if/when possible.

    Re: Finding the equation for a graph!

    Vertical Asymptotes at x=-9, 5 . → Factors of (x+9) and (x-5) in the denominator
    Horizontal Asymptote: y = 0 . → How does the degree of the denominator compare to the degree of the numerator?
    y-intercept: y=2 . → When x=0, y=2 .

    No x-intercept is shown.

    The answer to the problem is y=\frac{90}{45-4x-x^2}. I understand why the answer is why it is however I don't understand how I'm supposed to deduce this answer to the equation. I have provided all the information above regarding the question given in my textbook.

    Actually never mind. I understand the problem, just mixed up the negatives. Silly question really.
