Can you tell me how to graph a parabola of y | - 2 less than or = y < infinity
To graph a parabola with a y-intercept of -2 and opening upwards that extends from y=-2 to positive infinity, follow these steps:
1. Identify the vertex of the parabola which will be at (0, -2) since the y-intercept is -2.
2. Choose additional points to plot the parabola. Since the parabola opens upwards, you can pick a point to the right and left of the vertex. For example, (1, 1) and (-1, 1) are common choices.
3. Plot the vertex and the additional points on the graph.
4. With this information, you can now sketch the parabola passing through these points.
Remember that the parabola will continue upwards towards positive infinity.
