1) Find the linearization [.00 off (1:) = 111(1 + x) at a = 0. Use this linearizationto approximate f (0.1). 2) Find all critical points of y = 3x4 4x3 and identify them as local maximum points, local minimum points, or neither. 3) Find all local maximum and minimum points of y = 2 + 3x x3 by the second derivative test. 4) A cylindrical tank standing upright (with one circular base on the ground) has radius 1 meter. How fast does the water level in the tank drop when the water is being drained at 3 liters per second
