## Week 13 in Precalc 11

This week he learned how to graph reciprocal quadratic functions. When beginning these questions it is always easiest to start by graphing the original equation, in this example it is x squared minus 3. After graphing this draw a broken vertical line on the zeros or x-intercepts, because this graph has 2 solutions it will have 3 hyperbolas. The 2 “L” shaped hyperbolas hover right above the x-axis and almost touching the broken lines. The hyperbola on the bottom follows the same rules except it’s on the other side of the broken line.

example 1: $5^2$
example 2: $5^{-1}$
example 6: $\frac{2} {3}$
example 9: $\tan(\theta)=\frac{9} {12}$ $\sin(32^{\circ})=\frac{x} {2}$ $(\theta)=\cos^{-1}(\frac{3} {5})$
