So this question builds off of the last question where we identified that the function f of x equals absolute value of x minus two would give us the difference between the number of micrograms of vitamin cb8, which is x, and the recommended micrograms or consumption of two micrograms per day.
00:23
And in this particular question, we are asked to decide what an appropriate domain for x might be.
00:29
Now, in general, an absolute value function typically doesn't have a restriction on the domain.
00:35
But in this case, we're asking what can x be? and it's relevant because x in this case is how much we ate.
00:42
So it wouldn't make sense, for example, for us to have eaten negative amount of micrograms, or wouldn't make sense probably for us to eat a lot, a lot of micrograms.
00:53
Now, i don't know how many micrograms are in a typical serving of anything that i'm eating, but i'm going to go ahead and bet that i can't eat.
01:03
I can't eat less than zero micrograms...
