Recognize a function from a table of values. Sine functions and cosine functions have a domain of all real numbers and a range of 1 y 1. Find the zeros of a function.
The range of a function is all the possible values of the dependent variable y. Any number should work and will give you a final answer between 1 and 1 from the calculator experiment and from observing the curve we can see the range is y betweeen 1 and 1. The set of all y values of a function we scan bottom to top function.
The set of outputs is called the rangeof the function. To play this quiz please finish editing it. These won t be terribly useful or interesting functions and relations but your text wants you to get the idea of what the domain and range of a function are.
In this section we provide a formal definition of a function and examine several ways in which functions are represented namely through. Although each input can be sent to only one output two different inputs can be sent to the same output. For example consider the function f f where the domain is the set of all real numbers and the rule is to square the input.
