    You could use the mean value theorem to find the tangent line parallel to the secant line which joins x = -2 and x = 10.

    Your data gives a parabola with equation y=\frac{-x^{2}}{4}+27

    can you just use the graph to get the answer or do you have to work it out analytically?

    It's a multiple choice question, sport, so you get the answer any which way you can (even if that means getting rid of all the wrong ones so that last man standing has to be the correct one) - that's just the nature of multiple choice testing.
