Well what i have isnt right but this is as far as i got
u need to move everything to the top so: 1(x+1)^-1
and whole numbers = 0 so im at: x^-1
then i mult x*-1 and then take one off of the power
so im at -x^-2 for the derivative
then plug in the x from the point into that and get 0=m
then the y=mx+b
plug in 1=0*0+b so b should = 1
so the equation should be y=0x+1 to by tan to the first graph
im off somewhere and im sure its something easy but i dont see it yet
