John

My calculator said it, I believe it, that settles it

(a). y = x(x-3)(x+4)

Use formula y = product of the 1st and 2nd times the derivative of the 3rd plus product of the 1st and 3rd times the derivative of the 2nd plus product of the 2nd and 3rd times the derivative of the 1st Or multiply it out first Same answer

(b). y= 7x+17x^2+30x^3

(c). y= 5e^x+9inX-x^9+8
That makes no sense. Sorry! Edwin
