#3 Choose the end behavior of the graph of the polynomial function.
f(x) x(x3)(5x+2), I think I have to foil to get 5x^32x^2+15x+6 So I think this one rises to the left and falls to the right. Please let me know if I did these correctly. Thanks

drwls,
There is no = sign in your function definition. Is there a typing error?
The "end behavior" is determined by the sign of the x^3 term in this case.
