  1. assuming you meant

    16x^2 + 8x + 7, it's just a parabola, with its vertex at x = -b/2a = -8/32, or -1/4

    So, just evaluate f(-1/4) to find the minimum.

    Since the coefficient of x^2 is positive, there is no maximum. Of course, there may be other typos hiding in there.

    There are two solutions to | 16x - 5 | = 3. The greatest solution is ___. Since the expression, 16x - 5, can be either positive or negative, solve for both. 16x - 5 = 3 16x = 8 x = .5 -(16x - 5) = 3 -16x + 5 = 3 -16x = -2 x = 1/8
