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. WebNov 9, 2024 · You can solve quadratic equations by graphing, factoring, completing the square, & the quadratic formula. Graphing gives a good visual, but it is hard to find values of x from a graph with no equation. If factoring is hard, the quadratic formula (a shortcut for completing the square) helps.
