(5) Highlighted Rel Fr cell's value
Number Line
Number Line registers up to three equations or inequalities and displays
their number line graphs. The expression types that can be selected are
shown below.
x<a, x≤a, x=a, x>a, x≥a, a<x<b, a≤x<b, a<x≤b, a≤x≤b
The values that you input for a and b in the above expressions must be
within the ranges defined below.
