### What is Meant by the Quadratic Function?

In mathematics, the quadratic function is a function which is of the form f(x) = ax2 + bx+c, where a, b, and c are the real numbers and a is not equal to zero. When the quadratic function is plotted in a graph, the curve obtained should be a parabola. The parabola is a “U-Shaped Curve”. The parabola obtained may be facing upward or downward depending on the coefficient sign of “a”, but it may have a difference in their width or the steepness.
