A Quadratic Function is any function defined by a polynomial whose greatest exponent is two. The graph of any quadratic function is a U-shaped curve called a parabola. There are certain key features that are important to recognize on a graph and to calculate from an equation. Definitions: Forms of Quadratic Functions. A quadratic function is a polynomial function of degree two. The graph of a quadratic function is a parabola. A formula for the location of the vertex for a quadratic in general form can be found by equating the two forms for a quadratic. How features of the parabola for a quadratic function can be obtained is summarized below. Knowing that the vertex of a parabola is the lowest or highest point of the parabola gives us an easy way to determine the minimum or maximum value of a quadratic function.

Multiply by. So we essentially reflected the point -1,0 over to 3,0. Note: this means that the axis of symmetry is also. Start with the given formula. Complete the square for. Use the vertex form, , to determine the values of , , and. Plug in. Combine like terms. Use the form , to find the values of , , and. So we essentially reflected the point 0,-3 over to 2,

.

The values should be selected around the vertex. So the y-coordinate of the vertex is. Step 3 Reflect those two points over the axis of symmetry to get two more points on the right side of the axis of symmetry. So when , which gives us the point 2, Word Problems Word. Find the distance from the vertex to a focus of the parabola by using the following formula. Use the properties of the parabola to analyze and graph the parabola. Find , the distance from the vertex to the focus. Start with the given formula. Select a few values, and plug them into the equation to find the corresponding values. Find the directrix. Step 4 Plot all of the points found including the vertex.
