What is the difference between y=x+3 and y=x^2+3?

I am unsure how to go about answering this question as I don't know what it is asking. It is a subtraction (a literal difference) question or is it asking about the meanings of the two equations. Professional opinions?

What is the difference between y = x + 3 and y = x^2 + 3?

The answer to this question would depend on where the question was found. If it was in a section of a math text book dealing with the difference between polynomials the result would be x^2 + 3 - x - 3 = x^2 - x.

Else, if it was in a section about the degree of polynomials, the number of roots they can have, etc., there are many different answers possible.

It is quite difficult to give an opinion about what the question actually means without some background information.

I think they may be referring to the difference in graphs maybe? Like one x is a linear grqph whereas a squared x is a graph that looks like a u called a parabola
