First, for there being a regression, there should be parameters! I will assume 3000 and 1 are in this case

It is linear regression if you consider your "employee age squared" as a variable, so, strictly speaking, it is a linear regression only after a transformation.

In general, there are many ways to transform apparently non-linear models into linear ones by means of one of those (exponential, logs, roots, powers and so on...)
