Three different functional groups.

Explanation:

On the image above the three different functional groups are highlighted.

Here we have an amine group #-NH_2# (Green).

Here there is a Thiol group #-SH# (Blue)

and at last there are an carboxylic acid group #-COOH# (Yellow)

Then there are two methyl groups #-CH_3#. But those are normally not considered as "functional groups".
