An asymptote is a line that identifies the boundaries of a curve. As of pre caluclus 11, the y asymptote (horizontal)=0. The x asymptote (vertical) is a little bit more complicated. Looking at the y axis, identify where the point of line is at -1 and 1. In between these points is where the x asymptote will be.

Today we reviewed some key points on absolute values:

-The values are ALWAYS positive.

-When graphing, the linear or quadratic equation will never enter the negative area (y.) As shown below, the line reaches 0 on the y axis and reflects up.
