Blog #13- Recipricals

This week we were taught about reciprocals.

In this blog I will be teaching you how to draw reciprocals for a linear graph.

First step: Plot your points

Second step: figure out the x intercept

Third step: find the -1 and 1 on the y axis

Fourth step: graph the reciprocal

Fifth step: find the points


Blog #12- graphing absolute values.

This week in Pre-Calc 11, we learned how to graph absolute values. These can be applied to both linear and quadratic functions. This task is very easy to complete.

When graphing absolute values the quatratic or linear line will never go below the x intercept.

When the parabola has a absolute value it forms a W shape.

This all happens because absolute value can never be a negative.
