Precalc 11 – “Week 13”

This week in Precalculus 11 we learned about Absolute Value Functions. We have already done absolute values which is:

\mid-3x+5\mid=11

Which is 3x=6

x=2

Absolute values turn the equation positive. Therefore an Absolute Value Function can only be positive.

y=\mid-3x+5\mid

As you can see the blue line is y=-3x+5, and because absolute values need to be positive then the line cannot be below the x-axis, therefore it is flipped as you can see by the red line: y=\mid-3x+5\mid

Thank You for Reading!
