Question: 2. If y = x' + 4x+8, then y'(2) =. A. 2x +4 B. 8 C. 0 3. Differentiate f(x) = >x +1 x-1 A.

2. If y = x' + 4x+8, then y'(2) =. A. 2x +4 B. 8 C. 0 3. Differentiate f(x) = >x +1 x-1 A. y'= 15x 15x B. y'= (x - 1)2 10x' -15x2 -1 C. y'= (x- 1)2 4. Find the first derivative of y = (7x+ 3)* A. y'= 28 B. y'= 28(7x +3)3 C. y'= 4(7x+ 3)3 5. Differentiate the function of f(x) = (2x -1)(x+1)+ A. f'(x) = (x+1)2(10x-2) B. f'(x) = (x+1) (10x-2) C. f'(x) = (x+1)*(10x-2) 6. If f(x) = 3x4 _ 2 VX , then f(4) = A. 767 B. 575 C. 383
