In addition, since we can find a vertical line that intersects the graph more than once, we conclude that the graph is not a function. 7) A function, on the other hand, is a relation that produces one output for each given input. What is Meant by Well-defined and Undefined Function? Ans. endobj /SMask /None>> With this data, a student maps a relationship between forehand and hand in the form y = ax + b, provided both are constants. Here we can see that the graph of \(y=|x|2\) has a domain consisting of all real numbers, \(=(,)\), and a range of all y-values greater than or equal to \(2, [2,)\). Example 5: Solve the equations for y to determine if the equation defines a function.
