Frequently Asked Questions
The vertex is the highest or lowest point of a parabola, depending on whether it opens upward or downward. It is given by (h, k) where h = -b/(2a) and k = c - b²/(4a).
The axis of symmetry is a vertical line that passes through the vertex, dividing the parabola into two mirror images. Its equation is x = h.
If a = 0, the equation is not quadratic but linear. The calculator will show an error because a must be non-zero for a parabola.
