    Answer:

    (8, 0) and (-9, 0) are the x-intercepts

    Step-by-step explanation:

    The x-intercepts are where the graph intersects the x-axis.  That means that you need to find the values of x when f(x) = 0.

    f(x) = (x – 8)(x + 9) = 0

            x = 8 or x = -9

    So, (8, 0) and (-9, 0) are the x-intercepts
