X Intercepts Vertex Form - In order to find the zeroes, you must put the value of f(x) to zero and solve for both values of x. (x+a)(x+b) to find the vertex in this form, you must take the average of the zeroes of the equation. Graph of a parabola showing where the x and y intercepts, vertex, and axis of symmetry are for the function y = x2 + 4x + 3. The standard form of a quadratic function presents the function in the form.
