I have a question that says:
f={(-2,1),(0,-2)}
g= {(-2,-4),(2,-1),(6,7)}
Find g-f and its domain.
How do I do this?

Subtraction is a mathematical "operation". The relations f and g are "functions". Applying subtraction to these relations is covered under the topic of "operations on functions". To learn how to do this sort of exercise, try here.

Note: The "domain" of the subtraction will be the set of inputs (that is, of x-values) for which both of the functions are defined.

If you get stuck, please reply with a clear listing of your efforts so far. Thank you! ;)
