Math Problem Statement

Graph the equation y = |x| - 2. Let x = -3, -2, -1, 0, 1, 2, and 3. Find the following y-values. Then choose the correct graph of the equation to the right. Find the y-value for x = -3.

Solution

You are given the equation y=x2y = |x| - 2 and asked to find the corresponding yy-value when x=3x = -3.

To solve this:

  1. Start by calculating the absolute value of x=3x = -3: x=3=3|x| = |-3| = 3

  2. Substitute x|x| into the equation y=x2y = |x| - 2: y=32=1y = 3 - 2 = 1

So, when x=3x = -3, the yy-value is 11.

Here are 5 related questions for further exploration:

  1. What is the value of yy when x=0x = 0 for the same equation?
  2. How would you graph the equation y=x2y = |x| - 2 for values of xx from 3-3 to 33?
  3. How does the graph of y=x2y = |x| - 2 differ from the graph of y=xy = |x|?
  4. Can you find the x-intercept(s) for the equation y=x2y = |x| - 2?
  5. How do you interpret the transformation of the absolute value function caused by the "−2"?

Tip: The graph of y=x2y = |x| - 2 is a V-shape shifted downward by 2 units from the origin.
