# Polynomial graph

I gave my students a few polynomial equations, a few quick check sheets and asked them to find the degree, end behavior, zeros, if there were any multiplicities, the domain, and to sketch the polynomial graph. We did some more practice with various degree polynomials, ones that we first had to factor, and ones with multiplicities greater than 2.

### For this activity students could be given an example polynomial and have to fill out the table and determine the end behaviour before attempting to sketch the graph. Then an online tool could be used to find the actual graph to compare to their own.

### Precalculus will be moving beyond their introduction to functions and function notation from Algebra II and into a in-depth development .

### This time around, I felt like my Polynomial unit needed a bit more to it. Last term, my kiddos did a small version of a graphing projec.

Students match 10 equations to their graphs in this quick introductory activity to polynomial graphing. There are also 2 blank grids on the answer sheet where
