Find the derivative of the following. Show your solution. 1. y = -x2 + 3 2. s = 5t3 - 3+5 4x3 3. y = 3 - X 4. w = 3z-2 _ 1 Z 5. y = 6x2 - 10x - 5x-2 6. y = (3 - x2)(x3 - x+1) 7. y = (x2 + 1)(x+5+3) 8. g (s ) = Vs-1 Vs+1 9. v = (1 -t)(1+t2 )-1 10.y = x2 -4 x+0.5 11. y = (2x + 5)5 12. y = V3x2 - 4x + 6 13. f (x) = V2r -12 14. g (x) = (4x + 3)4(x +1)-3 -1 15. y = 21 (3x - 2)7 + 4 -: 1 2x2
