To graph the equation y = x^3 - 1, you can create a table of values or use a graphing tool.
Using a table of values:
Let's choose a few values for x and calculate the corresponding y values.
When x = -2, y = (-2)^3 - 1 = -8 - 1 = -9. Therefore, one point on the graph is (-2, -9).
When x = -1, y = (-1)^3 - 1 = -1 - 1 = -2. Therefore, another point on the graph is (-1, -2).
When x = 0, y = (0)^3 - 1 = 0 - 1 = -1. Therefore, another point on the graph is (0, -1).
When x = 1, y = (1)^3 - 1 = 1 - 1 = 0. Therefore, another point on the graph is (1, 0).
When x = 2, y = (2)^3 - 1 = 8 - 1 = 7. Therefore, another point on the graph is (2, 7).
Now that we have a few points, we can plot them on a graph and draw a curve that passes through these points.
