WebNov 9, 2024 · Graphing – this is a good visual method if you have the vertex form of a parabola or if you have a parabola-like curve from a data set. If you graph the quadratic function f(x) = ax 2 + bx + c, you can find out where it intersects the x-axis. The only drawback is that it can be difficult to find exact values of x. Also, the graph will not … WebThe general form of a quadratic function presents the function in the form f(x) = ax2 + bx + c where a, b, and c are real numbers and a ≠ 0. If a > 0, the parabola opens upward. If a < 0, the parabola opens downward. We can use the general form of a parabola to find the equation for the axis of symmetry.
