STANDARD FORM OF A QUADRATIC FUNCTION The standard form of a quadratic function is y = ax2 + bx + c where a, b and c are real numbers, and a ≠ 0.

To convert standard form to vertex form we follow the following procedure: -. First we have to take the common factors from the first two terms in the standard form f(x) = ax2 + bx + c. Now we complete the square of the first two terms by adding and subtracting square of the half of second term.

The vertex form of a parabola's equation is generally expressed as : y=a(x−h)2+k (h,k) is the vertex If a is positive then the parabola opens upwards like a regular "U". (same as standard form) If a is negative, then the graph opens downwards like an upside down "U".(same as standard form) If |a| < 1, the graph of the parabola widens.
