A solid lies between planes perpendicular to the x-axis at x = 0 and x = 17. The cross-sections perpendicular to the axis on the interval are squares with diagonals that run from the parabola to the parabola . Find the volume of the solid.

Heather is writing a quadratic function that represents a parabola that touches but does not cross the x-axis at x = -6. which function could heather be writing? fx) = x2 + 36x + 12 = x2 - 36x - 12 f(x) = -x + 12x + 36 f(x) = -x? - 12x - 36
