Answer the following:

EXERCISE II Find the slope of the given curve at the point indicated. 1. y = 8x - 3x2, (2,4). 2. y = x -x2+2, (-1,2). 3. y = x3 - 1, (0, -1). y = 8/x2, (2,2). y = x+ 2x-1, (2,3). 6. y = 2Vx, (-8,-4). 7. At what point is 2 the slope of the curve y = 4x + ? 8. At what points is 9 the slope of the curve y = x3 - 3x Find y' in each of the following. 1. y = x8(2x2 - 1). 2. y = (x - 1)(2x2 + 3). 3. y = ax2 + bx+ c. 4. y = 2x1/2 + 3x2/3. 5. y = 4x-8+ 3x-1 +7. 6. y = 1(x2 - x-2).7. y = Vx2 - 31/x - 5. 8. y = 2(x + 1)3. 9. y = x5 - 2x8 - 3 x2 10. y = (2 - x)(2x + 1) X In each of the following, find y' for the given value of z. 11. y = 2x3 - 3x2 - x + 5, * = 2. 12. y = (x - 1)(x + 3)2, x = -3. 13. y = 2v x(3x - 2), * = 4. 14. y = 3(Vx - 2)2, x = -8. 15. y = *+1 1 VX * = 7 16. y = (1 + Vx)(2+ Vx) x = 1. 17. y = xva - avx, x =a. 18. y = (x - a)(x2 - a2), x = a 19. y = Vax2 + Valx, x = a. x2 20. y = X =a
