Quadratic Functions

-->

A quadratic functions, in mathematics, is a polynomial function of the form

ƒ(x) = ax² +bx +c, a≠ 0.

The graph of a quadratic function is a parabola whose major axis is parallel to the y-axis.

Qudratic Functions are presented in three forms namely:-

General form

Factored form

Vertex form or the Standard form

The general technique for graphing quadratic functions is the same as for linear equations graphing However, since quadratics graph as curvy lines (called "parabolas"), rather than the straight lines generated by linear equations, there are some additional considerations.

Graph of quadratic functions are always a parabola either opening upwards or downwards.Also you can follow my blogs for Precalculus Tutorials. I hope this was useful.
