The answer I think is this
fx=x^2-3
By definition, the standard form of a polynomial is given by:

We then have the following polynomial:

Rewriting in its standard form we have:

We realize that the polynomial has three terms, therefore, it is a trinomial.
The largest exponent of the polynomial is three and therefore we have a trinomial of degree three.
Answer:

Three degree trinomial.
