Hi, I need help in using operations with functions. I'm familiar with functions of equations, (ex. f(x) = x^{2}, g(x) = x + 1, f + g = x^{2}+ x + 1),

but what I really need help in is understanding a problem like this:

f = {(-3, 1), (0, 4), (2, 0)}

g ={(-3, 2), (1, 2), (2, 6), (4, 0)}

What is f + g? f * g? g / f?
