Domain And Range Of A Negative Linear Function
Domain and range of a linear function that models a real world situation duration.
Domain and range of a negative linear function. I highly recommend that you use a graphing calculator to have an accurate picture of the. If you put for example 10 in you get. The domain of y sin x is all values of x since there are no restrictions on the values for x.
Linear functions have the domain and range of all real numbers. Put any number into the sin function in your calculator. The range of a simple linear function is almost always going to be all real numbers.
To find the range is a bit trickier than finding the domain. A negative number will never show for this function. Pine view middle school math 4 382 views.
Given a function find the domain and range of its inverse. A graph of a typical line such as the one shown below will extend forever in either y direction up or down. The range of a non horizontal linear function is all real numbers no matter how flat the slope might look.
Let s explore both of these scenarios. Its range is a sub set of its codomain. Sometimes however the domain and range of a linear function may be restricted based on the information it represents.
For example the function has a domain that consists of the set of all real numbers and a range of all real numbers greater than or equal to zero. 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 domain and range of linear functions is all real numbers or negative infinity to positive infinity.
