Graph y x2 2x 3

.

Now that we know the x-coordinate of the vertex, we can use it to find the y-coordinate of the vertex. Raise to the power of.

.

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.
