Step-by-step Solution
To construct a table of solutions for the equation \( y = x^3 - 1 \), we can choose a range of \( x \) values, calculate the corresponding \( y \) values, and then summarize the results in a table.
### Table of Solutions
| \( x \) | \( y = x^3 - 1 \) |
|---------|-------------------|
| -2 | \( (-2)^3 - 1 = -8 - 1 = -9 \) |
| -1 | \( (-1)^3 - 1 = -1 - 1 = -2 \) |
| 0 | \( 0^3 - 1 = 0 - 1 = -1 \) |
| 1 | \( 1^3 - 1 = 1 - 1 = 0 \) |
| 2 | \( 2^3 - 1 = 8 - 1 = 7 \) |
### Summary of Solutions
- For \( x = -2 \), \( y = -9 \)
- For \( x = -1 \), \( y = -2 \)
- For \( x = 0 \), \( y = -1 \)
- For \( x = 1 \), \( y = 0 \)
- For \( x = 2 \), \( y = 7 \)
### Graphing the Equation
To graph the equation \( y = x^3 - 1 \), you would plot the points from the table above on a coordinate plane. The graph of this cubic function will have the following characteristics:
- It will pass through the points listed in the table.
- The graph will be continuous and smooth, with a characteristic "S" shape.
- The function will have one real root at \( x = 1 \) (where \( y = 0 \)) and will extend to \( -\infty \) as \( x \) approaches \( -\infty \) and to \( +\infty \) as \( x \) approaches \( +\infty \).
If you have graphing software or a graphing calculator, you can input the function \( y = x^3 - 1 \) to visualize the graph.
Quick Answer
Create a table with \( x \) values and their corresponding \( y \) values for \( y = x^3 - 1 \). The table includes points like (-2, -9), (-1, -2), (0, -1), (1, 0), and (2, 7). The graph is a smooth cubic function with an "S" shape, passing through these points.
