Describe Domain And Range Of A Function
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.
Describe domain and range of a function. In algebra when we deal with points on a graph you may be asked to find its domain and range. When functions are first introduced you will probably have some simplistic functions and relations to deal with usually being just sets of points. A piecewise function can be graphed using each algebraic formula on its assigned subdomain.
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 we could write this as 1 y 1. When using set notation we use inequality symbols to describe the domain and range as a set of values. Let s learn what each of these mean.
The domain of y sin x is all values of x since there are no restrictions on the values for x. What is domain and range. For many functions the domain and range can be determined from a graph.
A piecewise function is described by more than one formula. Put any number into the sin function in your calculator. The domain tells us all the possible values of x the independent variable that will output real y values.
The range of the function excludes every function does which is why we use a round bracket. An understanding of toolkit functions can be used to find the domain and range of related functions.
