(1) Find the following derivatives.
(3) Suppose and Find all the values of x for which the slope of the tangent to at equals the slope of the tangent to at .
We are looking for all x that satisfy
f '(x) = g '(x)
(difference of two squares)
(difference of two squares again)
x = 2 or x = -2
Thus, x equals plus or minus 2 is the answer to the question.
