Find an equation of the tangent line to the curve at the given point:
And I am using the the formula:
lim as x approaches a = [f(x) - f(a)]/(x-a).
So plugging in what we already know, we get:
[x-1/x-2 - 2]/x-3 = slope of the tangent line
Sooooo I'm wasn't sure how to procede. I tried a few different things and I ended up like this:
So the first thing I did was make the 2 that was being subtracted from the first rational number: [2(x-2)]/(x-2). This would simplify the whole thing to:
[(x-1)-2(x-2)/(x-2)]/x-3. Then I brought the x-3 up:
Any help would be appreciated.
