Given the graph of the function "f", you need to find the approximate output value:

Notice that both values are closed to:

Therefore, you can use this formula:

In this case, you can approximate that:

Where "c" is a constant.
Its derivative is:


(a) In order to find:

You need to use:

Then, using the formula, you get:

(b) And for the other value:

Then:

Hence, the answers are:
(a)

(b)
