I am stuck on Q3,4,6,7,8,9,10,11 of the questions could anyone help? I have done Q1,2 &5.
Q3 - I can't see what gradient the book shows to I'll just refer to it as m. Anyway, you have y=1+xx so you need to find dxdy by using an appropriate differentiation rule that you should know. Set dxdy=m and solve for x to see at what x coordinates the gradient is m.
Once you have your value(s) of x, plug them back through y=1+xx to find your y coordinates.

I have tried this but only get one set of coordinates instead of two
When I differentiate using the quotient rule I get 1/(1+x)^2
