Question 482737
It's actually an S sideways, and there's no vertex, how can there by on an S shape?

If your using calculus to do this, you can get special points. 1) solve G(x) = 0, i believe x = 2 is the only solution (in real numbers anyway). Then differentiate G(x), and solve G'x = 0. Only solution should be x =0. Then using the derivative find out where the function increases and where it decreases. That should be ample info for a rough graph
