How do I solve this problem- I know it has something to do Riesz represenation but am having difficulty connecting dots(adsbygoogle = window.adsbygoogle || []).push({});

Conside R4 with usual inner product. Find the linear funcitonal associated to the vector (1,1,2,2).

What am I missing- is this problem complete or is there something else Also what does usual inner product mean.
