Week 12 – Graphing absolute value

This week, I have learned how to graph absolute values. The difference between last week and this unit, There is a lumps everywhere.


On the graph, you can see there is a lump in the middle. This is because of absolute value. when you add absolute value signs, the answer can’t be negative. As a result, there is a lump in the middle which is the new vertex.

This also works for the linear equation.

As you can see here, there is no negative value in this graph. This is because the equation is y=|x+2|.

Since there is the absolute value, the equation becomes positive.
