define for all x. Find the equation of the tangent line to the graph of at the point (2,13).
I know that for a function (I is a neighborhood of the point ) that is differentiable at , the tangent to the graph of the point is given by the equation:
To find the slope of the line, wehave
is the slope of this function is 2 then? I cannot figure out if this is correct and how to find the equation of the tangent line
and, as x goes to , that becomes . Although, as harish21 says, it is simpler to put the [tex]x_0= 2[tex], from the start.
You appear to be saying that . That is, that you are canceling the " only from second term. You can't do that, of course, is NOT equal to a+ 1.

Once you have that, use the formula you gave: with , , and .
