A curve has equation y = 3 + 12 2-x (i) Find the equation of the tangent to the curve at the point where the curve crosses the x-axis. (ii) A point moves along the curve in such a way that the x-coordinate is increasing at a constant rate of 0.04 units per second. Find the rate of change of the y-coordinate when x = 4.
