what is a 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. Using Vertex Form to Derive Standard Form. Write the vertex form of a quadratic function. y = a (x - h) 2 + k. Square the binomial. y = a (x 2 - 2xh + h 2) + k. y = ax 2 - 2ahx + ah 2 + k.

Important Notes on Quadratic Function The standard form of the quadratic function is f x ax 2 bx c where a 0 The graph of the quadratic function is in the form of a parabola The quadratic formula is used to solve a quadratic equation ax 2 bx c 0 and is given by x b b 2 4ac 2a
