Good evening! I would like to ask for the solution and answer for this. Thank you

Calculus 1 (Differential Calculus) Find the Maximum and Minimum points for each of the following curves. 1. y = = x3 - x2 - 2x 2. y = x3 - 9x2 + 15x -5 3. y = (x+ 1) 2 x 4. y =-5(x- 4)4+2Calculus 1 (Differential Calculus) Find the point of inflection for each of the following curves. 1. y = 5 - 2x - 3x2 - x3 2. y = x4 - 24x2 + 75 3. y = x(x2- 5)2 4. y = -4 - 3x - NIP - 2 2
