How to graph property of parabolas

The graph of any quadratic equation y=ax2+bx+c y = a x 2 + b x + c, where a, b, and c are real numbers and a≠0 a ≠ 0, is called a parabola.

When graphing parabolas, find the vertex and y-intercept.

Use the leading coefficient, a, to determine if a parabola opens upward or downward.
