Domain And Range Of A Function Infinity
The example below shows two different ways that a function can be represented.
Domain and range of a function infinity. According to the domain and range values we determined 0 0 could not be a part of the range for this function. Play this game to review algebra i. These can be slightly more demanding.
A table of domain and range of basic functions might be useful to answer the questions below. To find the domain of a function just plug the x values into the quadratic formula to get the y output. I am often asked what is the domain and range of a function.
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. 2 infinity we can check our answer by looking at the graph. The domain of a function is the collection of independent variables of x and the range is the collection of dependent variables of y.
To find the range of a function first find the x value and y value of the vertex using the formula x b 2a. In the example above the domain of f left x right is set a. Make a table of values on your graphing calculator see.
In the example above the range of f left x right is set b. First the definitions of these two concepts are presented. The domain of y sin x is all values of x since there are no restrictions on the values for x.
Again we could use interval notation to assign our range. The graph agrees with this conclusion. Put any number into the sin function in your calculator.
