anti differntiation, please answer the following questions. keep working out and explanation seperate please

5 For each gradient function graph below, give: i the value of x where the gradient is 0 ii the sign of the gradient (positive or negative) left of this point iii the sign of the gradient right of this point. a yA Gradient b YA function 47 Gradient function X C YA d YA Gradient - Gradient function function x 6 MC Examine the gradient function, f'(x), sketched at right. Then f'(x) choose the correct answer to the following questions about its original 3-1 function. a f(x) has a gradient of 0 when x equals: A 2 B -2 and 2 C 1 and 3 D 0 and 3 E 4 b f(x) has a negative gradient when: A x3 DX 0 -2- c f(x) has a positive gradient when: A x 3 B x> 1 and x 1 and x > 3 D x = 1 and x = 3 E x= 0
