In the previous module, you learned the general form y = ax^{2} + bx + c of a quadratic function and represented it in various ways. In this module, the standard form or vertex form y = a(x – h)^{2 }+ k will be introduced. There will be instances that the standard form of quadratic function will be more appropriate to use when working on problems involving the vertex of the graph of a quadratic function.

**LEARNING COMPETENCY**

The learners will be able to:

- transform the quadratic function in general form y = ax
^{2}+ bx + c into standard form (vertex form) y = a(x – h)^{2}+ k and vice versa.**M9AL-Ig-12**
