Figure 12.The vertical line test is a test that can be performed on a graph to determine if a relation is a function. Recall that a function can only be a function if every value of x maps to only one value of y, that is to say it's a one-to-one function or a many-to-one function. If every value of x only has one value of y, any vertical line drawn on ...One way is to look at the graph and see if there is a line or curve. If there is more than one line or curve, then the graph is not a function. Another way to determine if a graph is a function is to look at the equation of the graph. If the equation has an x squared term or any other term that is not linear, then the graph is not a function.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 ).A graph provides a visual method of determining the limit of a function. If the function has a limit as \(x\) approaches \(a\), the branches of the graph will approach the same \(y-\) coordinate near \(x=a\) from the left and the right. See Example.
