A parabola is a special curve shaped like an arc. The **standard form** of a parabola is y = ax^{2} + bx + c. The **vertex form** is y = a(x-h)^{2} + k, where (h,k) is the vertex. If a > 0, then the parabola opens upwards. If a < 0, then it opens downward.

Good to know! If the absolute value of a < 1, the graph of the parabola widens. If the absolute value of a > 1, the graph becomes narrower.
