For b): The value of the function is the length of the segment.
For part c, you use the tangent line atany hints as to how to answer c and d?
those are where I am absolutely at a loss -
c: I mean, would you find like??
and what are they even asking for d - and actual number?to approximate the value of the function at
. In the drawing you have, this approximation is given by the length of
. But the formula for this approximation is
, which simplifies to
in this case.
For part d, this is simply. It doesn't help you a whole lot except that as h approaches zero, this is the derivation of the derivative of
at a.
