Derivative of 2x^2.9 - 3x^3.4 + 19

[JayDub]

if y = 2x^2.9 - 3x^3.4 + 19

the derivative?
y' = 2(2.9)x ^ 1.9 -3(3.4)x^2.4 + 0
y' = 5.8x^1.9 - 10.2x^2.4

 

[Pengwuino]

Yes that's correct

 

[JayDub]

and then the y'' of that would be...

y'' = 11.02x^0.9 - 24.48x^1.4?

 

[Pengwuino]

Yes, that's right
