How did they get that answer? '(f-g)(x) is set of 3 points'?

I thought I knew this stuff, but when I got to the review they are asking for ordered pairs... I don't understand how they got to the "acceptable answer". Can anyone help me out? I'd really appreciate it.

Thanks!

I don't understand how they got to the "acceptable answer".

Unless they specified lists of points as being the domains of each of f(x) and g(x), their "acceptable answers" are not correct. :shock:

(f - g)(x) means f(x) - g(x)

(f*g)(x) means f(x) * g(x)

None of your acceptable answers make sense in this context.
