Graph y x2 2x 3

.

Substitute the known values of and into the formula and simplify. Plug in and. To find the x-coordinate of the vertex, use this formula:.

.

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. X-Intercepts The x-intercepts are the values of x that intersect the y-axis. A parabola has two x-intercepts.

So the x-coordinate of the vertex is. Find the properties of the given parabola. Multiply and to get. Algebra Examples Popular Problems. Simplify by subtracting numbers. So when , which gives us the point 2, Find the vertex. Start with the given equation. The values should be selected around the vertex. Plug in. Substitute the values of , and into the formula. Username: Password: Register in one easy step! Substitute the known values of and into the formula and simplify. In Depth In. Since the value of is positive, the parabola opens up.

.

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. 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. Also, the vertex is at the axis of symmetry of the parabola ie it divides it in two. In Depth In. Enter a problem 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. Multiply and to get. 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. Divide by. Log in or register.
