Please provide easy to read solutions for the following. Thank you

1. (6 points) Consider the function f(x) = 24 - 4x3. (a) (3 points) Find the intervals where the function is increasing, the intervals where it is decreasing, and the x-coordinates of any local maxima or minima. (b) (3 points) Find the intervals where the function is concave up, the intervals where the function is concave down, and the x-coordinates of any inflection points.2. (4 points) Find the global maximum and global minimum of the func- tion f(x) = 3 - 6x2 + 22 on the interval [-1, 1]. Be sure to show your work, and state both the maximum/minimum and the inputs which give them. (So your answers should be something like "a maximum of *blah* at x =*blah*> )
