Good evening, need a little help please.......I need to find the derivative of f(x)=2x^-3-3x^-2. Thanks

OpenStudy (anonymous):

this is a power rule: -6x^(-4) + 6x^(-3)

OpenStudy (anonymous):

use the all mighty power rule. \[f(x)=2x^2-3x^{-2}\] \[f'(x)=4x+6x^{-3}\]

OpenStudy (anonymous):

oops typo sorry. i read \[x^3\] when it should have been \[x^{-3}\]

TBates is right and i am wrong!
