Thread: deritive by limit process

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

as i solve this my main problem is with the simplifying algebra part.....i havent taken math in so long i just dont know what i should do first on certain parts as i work thru this... i ended up with the awnser m = -1 is this correct?

No one can tell you whether your answer is correct if you don't tell us what the question was! I guess from your title that you want to find the derivative of this function but at what x?

the problem says find the derivative by the limit process...

and gives me the equation f(x) = 1/(x-1)
