Note: It is a common error to call any u-shaped curve a parabola. A parabola must satisfy the conditions listed above, and a parabola always has a quadratic equation. Example: For the quadratic function , identify the vertex, the y-intercept, x-intercept(s), and the axis of symmetry. Graph the function. Graph the points identified above: vertex, point on . y-axis, points on. x-axis. Then draw the smooth curve of a parabola through the points. The . y-coordinate of the vertex represents Parabolas are of course not the only non-linear curves of importance - others being e.g. x 2+y = 1 (circle), x 2 4 + y 9 = 1 (ellipse), xy = 1 (hyperbola) - but they are the only ones discussed here. The shape of the parabola will be obtained experimentally i.e., by plotting enough points to see what the curve looks like. A second technique to identifying the curve of the parametric equations is to try to eliminate the parameter from the equations. This will result in an equation involving only x and y which we may recognize. For example, let's look again at the previous example. Since x = 2t then solving for t gives t = x/2. A parabola opening up has a minimum, while a parabola opening down has a maximum. All of the points on a parabola define a parabola. However, the vertex is the point in which the y value is only used for one point on the parabola. A parabola is a single curve: it does not have separate parts.

The vertex of any parabola has an x-value equal to − b 2 a. After finding the x-value of the vertex, substitute it into the original equation to find the corresponding y-value. This y-value is a maximum if the parabola opens downward, and it is a minimum if the parabola opens upward. We can easily identify that the parabola is opening left or right. Since the coefficient in front of the x term is positive, we can say that the parabola will open to the right. The focus will be to the right of the vertex, and the directrix will be a vertical line that is the same distance to the left of the vertex that the focus is to the right. In Exercises 37–40, write an equation of the parabola shown. (See Example 4.) 37. 39. In Exercises 41–46, identify the vertex, focus, directrix, and axis of symmetry of the parabola.
