Hey, any help with this is appreciated, thanks. ^^

Question 1:

Find the coordinates of any points on this curve where the gradient is stated.

Y = x^2 + 3 / 2x^2, gradient = 3

(it's a fraction, I just don't know how to make those)

Question 2:

Given that the curve with equation y=Ax^2 + Bx has gradient 7 at the point (6,8), find the values of the constants A and B.

Question 3:

The two tangents to the curve y=x^2 at the points where y = 9 intersect at the point P. Find the coordinates of P.

Question 4:

Find the values of x at which the gradient of the curve

y = x^3 - 6x^2 + 9x + 2 = 0

Thanks again ^^
