Question

Find d2y/dx2 if y=6x^2+10x+3x^-3

Answer 1

12x^5-36/x^5

Answer 2

thanks! but how did u get that??

Answer 3

do u know differentiation

Answer 4

\[6x ^{2}+10x+3x ^{-3}\]
dy/dx=\[12x+10-9x ^{-4}\]
so d^2y/dx^2=\[12+36x ^{-5}\]

Answer 5

do u get it now

Answer 6

yes, thank you so much! :)

Answer 7

ur welcome
