SP#2: Unit E Concept 7 - Graphing a polynomial and identifying all key parts

This problem is about graphing polynomails, including the x and y intercept (with multiplicities), end behavior. 
To begin with, I factored out the equation above which lead me to my zeros. My original equation was to the 4th power which means I need 4 zeros. When i factored out the equation, I ended up with 4 zeros. Also, since the original equation started with "x^4" (both positive = even positive) the graph will be going up whether it's going to infnity or negative infinity. We find the y-intercept by setting "x" to 0 in the original equation. After all that, we plot all the points given, and make sure the graph is going upwards both ways. :)
