1. Remember. The derivative of a function at a particular point represents theslope. So find y' and plug in x = 1/2 to get your slope. Then, use the point slope form of a line to get your tangent line: where is your point P.

2. Plug in Q(2,0) into your tangent line equation to see if there is an equality. Do the same for C.

3. What shaded area?
