I just need to know the process, do I use the Difference Quotient?

OpenStudy (luigi0210):

@primeralph this is easy for you

OpenStudy (johnweldon1993):

I would just find the derivative using the power rule...and the plug x = 7 in for the 'x' afterwards

OpenStudy (anonymous):

so whats the power rule?

OpenStudy (luigi0210):

@ChandlerT0125 are you in Pre-cal or calc?

OpenStudy (anonymous):

pre-calc

OpenStudy (luigi0210):

Ah, then you have to use the difference quotient

OpenStudy (luigi0210):

@johnweldon1993 they don't learn that till later

OpenStudy (johnweldon1993):

Yeah do what you are learning first :)

so I used the difference quotient and I got as my final answer |dw:1374596682532:dw|
