#1
ok 2 things, Im working through some past papers for C1 from solomon and im just wandering if you anyone has the mark schemes? In particular im looking for mark schemese to papers: D,F,G,H,I.

secondly im stuck on question 9, paper G. it does seem like a kinda hard question for C1, or maybe its just a mind block i have. anyway heres the question.
Code:
```9.
The Curve C has the equation y=f(x) where

f'(x) = 1 + 2/Sqrt(x)

The straight line L has the equation y= 2x - 1 and is a tangent to C at the point P.

a) State the gradient of C at P.
b) Find the x-coordinate of P.
c) Find an equation for C.
d) Show that C crosses the x-axis at the point (1,0) and at no other point.```
a) 2.
b) x=4.
c) ?
d) ?

thanks rev.
