A cliff diver's height above the water, in meters, is modeled by the function h (d) = - d^2+2d+24, where d represents how far the diver is from the cliff. How far from the cliff will the diver be when she reaches the water

    H (d) = height from water

    when he reaches the water, his height from water=0

    so set the equation equal to zero and solve

    0=-d^2+2d+24

    multiply both sides by - 1 for ease

    0=d^2-2d-24

    now find what 2 factors of - 24 add up to - 2

    answer is - 6 and 4

    0 = (d-6) (d+4)

    set each to zero

    d-6=0

    d=6

    d+4=0

    d=-4

    you cannot have negative distance because that means he hasn't jumped yet so get rid of this number

    d=6

    answer is 6 meters
