Question

Study this equation carefully. What classification should this reaction have?

Cu + 2AgNO3 Cu(NO3)2 + 2Ag

Answer 1

i'm not sure about the "classification" part, but i think it's a single displacement reaction :)

Answer 2

He is right, it is a single-displacement reaction.

Single-displacement reactions take the general form of:
A + B-C --> A-C + B
In your equation, the Copper atom is the "A" in this reaction and the "B-C" is the AgNO3
