    y=-(x+2)(x-5) is a downward facing parabola with x-intercepts (-2) and (5)

    Thanks:) So what would be the range?

    to find range, first find the axis of symmetry, which is the x value exactly between -2 and 5

    would that be 1,9

    not quite what number is exactly halfway between -2 and 5?

    1 and 2

    nope, 3 is closer to 5 than -2

    right, so our axis of symmetry is x = 1.5 now, to find our range, find f(x) when x = 1.5
