It tells us, given the allowed inputs into our function, what would the function output? So here, they're saying, look, what gets output when we input x is equal to negative 1? Circle is a set of points. It is not a function. The question is: can the circle be a graph of a function of one variable, i.e. mapping real x from some domain into a real y? Answer: there is no such function, because (as you noted) a single value (say x = 1 / 2) would need to map into multiple variables (say y = ± √3 / 2 ).Let’s look at some examples below, at how to identify a function. Example #1 :Function Maps. Example #2: Tables. Example #3: Graphs. In order to know if a function is a function when looking at graph, we perform something called a Vertical Line Test.
