Before getting into the topic of domain and range let s briefly describe what a function is.

Domain and range of a function examples. Actually differentiability at a point is defined as. To see that we observe that the natural domain of this function is 1 since we request that the expression from which we extract the square root is non. Access free domain and range of a function interactive worksheets. Differentiability applies to a function whose derivative exists at each point in its domain.

The range of a function is all the possible values of the dependent variable y. The domain of y sin x is all values of x since there are no restrictions on the values for x. Differentiability of a function. 9 range of a function definition.

The range of a function f consists of all values f x it assumes when x ranges over its domain. 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. Domain and range of a function explanation examples. Suppose f is a real function and c is a point in its domain.

Put any number into the sin function in your calculator. Sometimes it isn t possible to list all the values that x or y can be because the graph. The range of f x 2 x 1 is 2. Remember that domain refers to the x values that are represented in a problem and range refers to the y values that are represented in a problem.

In this article we will learn what a domain and range of a function mean and how to calculate the two quantities.
