Hi, thank you for your help.

i have being given this question to do, i have done the first part but am unsure about the nxt parts..

I have y=3x^4+4x^3

i had to find dy/dx = 12x^3+12x^2

Then i need to show that the graph of the function y has stationary points at x=0 and x=-1, and find their co ords.

Then i have to find if these points are min max or stationary, which i know how to do by the gradient function(the table thing not sure of its name)

If you can explain how to do the second part that would be great. thank you
