Standard form: y = ax2 + bx + c
Graphing form: y = a(x− h)2 + k
Factored form: y = a(x + b)(x + c). g

At the skateboard park, the hot new attraction is the U-Dip, a cement
structure embedded into the ground. The cross-sectional view of the U-Dip
is a parabola that dips 15 feet below the ground. The width at ground level,
its widest part, is 40 feet across. Sketch the cross-sectional view of the UDip, and find an equation of the parabola that models it.
