1) Differentiation question:-

Find the values of 'x' for which the gradient of the curve y=3+4x-x^2

is equal to a) -1

b) 0

c) 2

I started this and got to dy/dx = 4-2x then stuck help!

2) Integration question:-

Integrate with respect to 'x'

a) 1 divided by the square root of 'x' (1/sqrt 'x')

Please feel free to explain your answers as i would like to learn/understand the method of solving involved.
