This calculator will find either the equation of the parabola from the given parameters or the axis of symmetry, focus, vertex, directrix, focal param. Converting an equation to vertex form can be tedious and require an extensive degree of algebraic background knowledge, including weighty topics such as factoring. The general form of the quadratic function is f(x) =ax 2 + bx + c to convert the standard form(y = ax 2 + bx + c) of a function into vertex form(y = a(x - h) 2 + k), we have to write the equation in the complete square form and vertex(h, k) is given by.
