10. Determine whether the given function satisfies the conditions of the Mean Value Theorem on the given interval. If so, find all numbers c that satisfy the conclusion of the theorem. (a) f ( x ) = 2 x 2 - 3 x + 7, on x [0 , 2] (b) f ( x ) = 2 ln x , on x [1 , 4] (c) f ( x ) = tan 2 ( πx ), on x [0 , 1] (d) f ( x ) = 1 - 3 x 2 , on x [0 , 1] 11. For the given function find the following: (i) critical points; (ii) intervals of increase and intervals of decrease; (iii) points of local maximum and local minimum. (Note: If the domain (typically, an interval) is not provided, start by finding the domain of the gvien function — you’ll need it!)

For the given function, find the following: (i) the intervals where its graph is concave up and where it is concave down; (ii) points of inflection. (Note: If the domain (typically, an interval) is not provided, start by finding the domain of the gvien function — you’ll need it!) (a) f ( x ) = x 4 + 2 x 3 (b) f ( x ) = x 2 x 2 + 4 (c) f ( x ) = 2 x 2 - 3 x + ln x (d) f ( x ) = ( x + 7) e x (e) f ( x ) = 3 x - 6 arctan x (f) f ( x ) = 2 x 2 + 8 cos x , on x [0 , 2 π ] 13.
