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.

Also, the vertex is at the axis of symmetry of the parabola ie it divides it in two. Since the value of is positive, the parabola opens up. Multiply 2 and to get. Answers archive Answers. Enter a problem Start with the given formula. Now that we know the x-coordinate of the vertex, we can use it to find the y-coordinate of the vertex. The directrix of a parabola is the horizontal line found by subtracting from the y-coordinate of the vertex if the parabola opens up or down. Cancel the common factor. Substitute the values of , and into the formula.

.

Simplify the result. Rewrite the expression. Cancel the common factor of. Cancel the common factors. Complete the square for. Factor out of. So we essentially reflected the point 0,-3 over to 2, Quadratics: solvers Quadratics. 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. Combine like terms. Step 5 Draw a curve through all of the points to graph the parabola. Substitute the known values of , , and into the formula and simplify. Use the vertex form, , to determine the values of , , and. Replace the variable with in the expression. Simplify the right side.
