You didn't really show that you made an attempt at a solution.

For b, try creating yourself a function (ie, maybe you can create a function g such that g(x) = f(x) - x). You know the sum of two continuous functions is continuous, so you can apply the IVT here.

2 is just conic sections (I believe that's what they are called) and you can figure it out by simply playing with the equations. Though you may want to draw some rough pictures to see what is going on.
