Answer:

See below

Step-by-step explanation:

  • The graph is attached with x-intercept and y-intercept indicated

To find x-intercept we solve x when y = 0

  • x^3 - 1 = 0
  • x^3 = 1
  • x = 1

Point is (1, 0)

To find y-intercept we solve y when x = 0

  • y = 0^3 - 1
  • y = -1

Point is (0, -1)

The function has no restrictions and its domain and range are all real numbers.

Interval notation for both domain and range is:

  • (-∞, +∞)
