That is called the range of the function.
Outputs that the function could actually produce? And we have a name for that. The focus of this video is, okay, we know the set ofĪll of the valid inputs, that's called the domain,īut what about all, the set of all of the Thing to think about, and that's actually what Is outside of the domain and try to input it into this function, the function will say, 'hey, wait wait,' 'I'm not defined for that thing' 'that's outside of the domain.' Now another interesting Outside of the domain, let me do that in a different color. If this is the domain here, and I take a value here,Īnd I put that in for x, then the function is A domain is the set of all of the inputs over which the function is defined.
To product an output that we would call 'f(x).' And we've already talked a little bit about the notion of a domain. It is going to map that, or produce, given this x, it's going 'f', but 'f' is the letter most typically used for functions, that if I give it an input, a valid input, if I give it a valid input,Īnd I use the variable 'x' for that valid input, it is A review, we know that if we have some function,
