derivatives

[uniqueownz]

using the definition, find the derivative of the following function:

f(x) = x / (5x - 1)

definition of a derivative = [ f(x+h) - f(x) ] / h

 

[stapel]

using the definition, find the derivative of the following function:

f(x) = x / (5x - 1)

definition of a derivative = [ f(x+h) - f(x) ] / h

So you've plugged "x + h" into f, simplified, subtracted f(x) from the result, divided by h, and... then what?

Please be complete. Thank you!
