    1)
    a) The graph shows that as more miles are hiked, the elevation increases until it begins to drop once a certain number of miles have been hiked. AT every point in the domain of e(x), if e(x) is decreasing than e'(x) is decreasing.
    b) At the highest point, the elevation stops ascending and then starts to descend (Increasing to decreasing)
    c) f'(x) = 250x-18.75x^2
    d) 0 = 250x-18.75x^2
    0 = (250 – 18.75x) x
    250 = 18.75x
    x = 250/18.75
    x = 13.333
    e) 125(13.333)^2 – 6.25(13.333)^3 = 7407 feet

    I agree with the answer , which mathematic property/rule did you use to change 125x^2-6.25x^3 to 250x-18.75x^2?
