Hello, all materials needed should be there. All error messages should be removed, I need help with my final study guide for my calc class. Your help is much appreciated.

. (8 pts) Find the derivative of the function. f(x) = (x3 2x + 1)7 . (10 pts) Critical Points: Using the derivative find the xcoordinate of all extreme points of the given function. Determine using algebra (first or second derivative test) Whether the point is a relative maximum, minimum, or neither. f(x)="22+2x7 3. (8 pts) Curve Sketching: Graph the J 1 i3 _ i 1 . critical points of the following function. Remember that between I Q - J each maximum and minimum there is an inection point. Then sketch ' the graph of the derivative
