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.

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. Since the value of is positive, the parabola opens up. Use the form , to find the values of , , and. Use the vertex form, , to determine the values of , , and. Divide by. Let's go through these steps in detail Jump to Top of Page Step 1 Finding the vertex: In order to find the vertex, we first need to find the x-coordinate of the vertex. Cancel the common factor. Step 1. Complete the square for. Enter a problem Negate to get. Graph the parabola using its properties and the selected points. So we essentially reflected the point -1,0 over to 3,0. Step 4 Plot all of the points found including the vertex. Table of Contents: Step 1: Finding the Vertex Step 2: Finding two points to left of axis of symmetry Step 3: Reflecting two points to get points right of axis of symmetry Step 4: Plotting the Points with table Step 5: Graphing the Parabola In order to graph , we can follow the steps: Step 1 Find the vertex the vertex is the either the highest or lowest point on the graph.

Find the value of using the formula. Use the form , to find the values of , , and. Log in or register. In Depth In. Divide by. Use the properties of the parabola to analyze and graph the parabola. Simplify the right side. 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. Find the axis of symmetry by finding the line that passes through the vertex and the focus. Consider the vertex form of a parabola. Cancel the common factor of. Raising to any positive power yields.
