Question

1. Drag the probe until x = 3. What do you notice about the values of the three functions?

Answer 1

1) Comparing those absolute value functions we have

With the linear function y= 2x -3:

The question is asking us what happens if we drag the probe until x= 3

If we drag the probe until x=3, then the three functions will have this same common point at x=3. The values for x=3 are the same (y=3)

Tables

y=2x -3

x | y
