X 2 2x graph

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.

Substitute the values of , and into the formula. Find the value of using the formula. Raising to any positive power yields. Algebra Examples Popular Problems. 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. Factor out of. Raise to the power of. Plug in. Also, the vertex is at the axis of symmetry of the parabola ie it divides it in two. So the first point to the left of the axis of symmetry is -1,0 Let's find the y value when Start with the given equation. 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. 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. Select a few values, and plug them into the equation to find the corresponding values. Find the vertex.

Consider the vertex form of a parabola. 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. Username: Password: Register in one easy step! Rewrite the expression. Substitute the known values of and into the formula and simplify. Start with the given equation. Graph the parabola using its properties and the selected points. Find the axis of symmetry by finding the line that passes through the vertex and the focus. Cancel the common factor of and. So we essentially reflected the point 0,-3 over to 2, Also, the vertex is at the axis of symmetry of the parabola ie it divides it in two.
