Graph it first, so you can know what type of polynomial it is.

How am I supposed to graph it if my calculator is broken :( I know how to solve these but my calculator is broken and I can't find any way to do it online. I just need someone to input the data for me and help me out, basically like I'm borrowing your calculator.
