Graph y x2 2x 3

.

To find the x-coordinate of the vertex, use this formula:. Find the focus. The focus of a parabola can be found by adding to the y-coordinate if the parabola opens up or down.

.

The important points are x-intercepts -1, 0 and 3, 0 , y-intercept 0, -3 , and the Vertex 1, The graph of a quadratic equation is a parabola. Axis of Symmetry The axis of symmetry is an imaginary line dividing the parabola into two equal halves. Substitute the given values for a and b into the formula for the axis of symmetry. Vertex The vertex is the maximum or minimum point of a parabola. Substitute 1 for x into the quadratic equation and solve for y.

Simplify each term. Also, the y-value for which is two units from the axis of symmetry is equal to the y-value of which is also two units from 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. Substitute the values of and into the formula. Simplify by subtracting numbers. To find the x-coordinate of the vertex, use this formula:. Log in or register. Simplify by adding and subtracting. Substitute the values of , , and into the vertex form. Step 4 Plot all of the points found including the vertex. So the x-coordinate of the vertex is. Note: this means that the axis of symmetry is also. Negate to get.

.

Raising to any positive power yields. 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. Consider the vertex form of a parabola. Log in or register. The values should be selected around the vertex. Enter a problem Plug in. Start with the given formula. Cancel the common factor of and. Substitute the values of and into the formula. Rewrite the expression. So we essentially reflected the point 0,-3 over to 2, Lessons Lessons.
