Functions of a Real Variable, chapter I, § 2. THE MEAN VALUE THEOREM

Here again, in the statement of th. 2 one can replace the interval $[a, b[$ by ] $a, b]$ and "right derivative" by "left derivative".

Bourbaki puts the proof directly after the statement, so what is above is the statement and its proof together.
