Ask HN: A noob question about exponential growth

Hi, I just wrote a reply to another comment and wrote something like: "I hope you have an above-average day today"

My question:

If every day from now on is an 'above-average day', would you call this an exponential growth?

Over all speaking, I'm aware that this would not be a 'continous graph'.

Edit:
