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.

Start with the given formula. Step 5 Draw a curve through all of the points to graph the parabola. Plug in. Cancel the common factor of and. So we essentially reflected the point -1,0 over to 3,0. Raising to any positive power yields. Consider the vertex form of a parabola. Rewrite the expression. Please ensure that your password is at least 8 characters and contains each of the following:. Cancel the common factor of. Word Problems Word. Step 2 Once you have the vertex, find two points on the left side of the axis of symmetry the line that vertically runs through the vertex. Reset your password if you forgot it. So when , which gives us the point 2, Also, the vertex is at the axis of symmetry of the parabola ie it divides it in two.

.

So the second point to the left of the axis of symmetry is 0,-3 Jump to Top of Page Step 3 Reflecting the two points over the axis of symmetry: Now remember, the parabola is symmetrical about the axis of symmetry which is This means the y-value for which is one unit from the axis of symmetry is equal to the y-value of which is also one unit from the axis of symmetry. Divide by. Find , the distance from the vertex to the focus. Simplify the right side. Substitute the known values of , , and into the formula and simplify. Substitute the values of , and into the formula. So we essentially reflected the point 0,-3 over to 2, Cancel the common factors. Cancel the common factor. Find the vertex. Substitute the known values of and into the formula and simplify. Raise to the power of. In Depth In. Consider the vertex form of a parabola. Multiply by.
