find the eqaution of the tangent line to the graph of f(x)= x+1/x-1 and x=2

OpenStudy (anonymous):

yea but how do you find tangent line

OpenStudy (anonymous):

well the tan of x=2 is 0

OpenStudy (anonymous):

did that help?

OpenStudy (anonymous):

lol nah.

OpenStudy (anonymous):

1 sec then

OpenStudy (anonymous):

what exactly are you needing?

OpenStudy (anonymous):

a work problem or a definition?

OpenStudy (anonymous):

need to find a tangent equation from the given info

OpenStudy (anonymous):

what is the given info?

OpenStudy (anonymous):

f(x)= x+1/x-1 and x=2

OpenStudy (anonymous):

it looks like the slope at x=2 would be 1
