Precalc 11 – “Week 14”

This week in Precalculus 11, we learned about graphing reciprocal functions. The hardest part about this was graphing quadratic reciprocal functions, because there are three different forms depending on how many roots it has.

Here are the three different ways:

1.Contains one roots:

y=\frac{1}{x^2+6x+9}

 

2.Contains two root:

y=\frac{1}{x^2+6x-9}

3.Contains zero roots:

y=\frac{1}{-x^2+10x-30}
