Find an equation of the tangent line to the curve at the given point.
The Attempt at a Solution
I've had several attempts at this, all of them are wrong. My solution book says the answer should be y=-x+5
One attempt I made is:
lim as h->0 [(3+h-1)/(3+h-2) - (x-1)/(x-2)]/h
lim as h->0 [(h+2)/(h+1) - (x-1)/(x-2)]/h
and I lost track of where I wrote the next step to this attempt. I've already attempted this 4 times.
