Math Problem Statement

List the intercepts of the equation yequalsx cubed minus 1.

Solution

To find the intercepts of the equation y=x31y = x^3 - 1, we need to determine both the x-intercepts and the y-intercept.

1. Y-intercept:

The y-intercept occurs when x=0x = 0.

Substitute x=0x = 0 into the equation:

y=(0)31=1y = (0)^3 - 1 = -1

So, the y-intercept is at the point (0,1)(0, -1).

2. X-intercepts:

The x-intercepts occur when y=0y = 0.

Set y=0y = 0 and solve for xx:

0=x310 = x^3 - 1 x3=1x^3 = 1 x=13=1x = \sqrt[3]{1} = 1

So, the only x-intercept is at the point (1,0)(1, 0).

Final Answer:

  • Y-intercept: (0,1)(0, -1)
  • X-intercept: (1,0)(1, 0)

Here are 5 questions that build on this information:

  1. What are the intercepts of the equation y=x24y = x^2 - 4?
  2. How do you find the intercepts of a quadratic equation?
  3. Can an equation have more than one y-intercept?
  4. What do the intercepts tell us about the graph of a function?
  5. What are the x-intercepts of the equation y=x416y = x^4 - 16?

Tip: When solving for intercepts, always set the opposite variable to zero (for y-intercept, set x=0x = 0; for x-intercepts, set y=0y = 0).
