Hi I put this equation in the graphing calculator and the equation part I am fine with its just that the graph looks weird and I do not know how to graph it correctly. I have been losing points for this and a whole lot of points last few tests. Please show / detail how to graph step the step with specific points. Thanks!

a) y = x^3 + 2x^2 and y = -(x^3+2x^2)

Thanks in advance
