The domain of a function is the set of all values of x for which f(x) is defined. One of the following sets is the domain for the function graphed below. Which set is it? Please hurry! See image for the problem & answer choices.

Aprobability experiment is conducted in which the sample space of the experiment is s={7,8,9,10,11,12,13,14,15,16,17,18}, event f={7,8,9,10,11,12}, and event g={11,12,13,14}. assume that each outcome is equally likely. list the outcomes in f or g. find p(f or g) by counting the number of outcomes in f or g. determine p(f or g) using the general addition rule.
