Find The Domain And Range Of The Function Graphed Below In Interval Notation
Because the domain refers to the set of possible input values the domain of a graph consists of all the input values shown on the x axis the range is the set of possible output values which are shown on the y axis keep in mind that if the graph continues beyond the portion of the graph we can see the domain and.
Find the domain and range of the function graphed below in interval notation. It never gets above 8 but it does equal 8 right over here when x is equal to 7. The function never goes below 0. It does equal 0 right over here.
The range is all the values of the graph from down to up. 6 5 4 3 n 1 6 5 4 3 2 1 1 1 2 3. Another way to identify the domain and range of functions is by using graphs.
Note that the domain and range are always written from smaller to larger values or from left to right for domain and from the bottom of the graph to the top of the graph for range. A curve a vertical dashed line and a horizontal dashed line are graphed. Domain range and graphs a function assigns values from an input set to distinct values in an output set.
F of 7 is 8. When looking at a graph the domain is all the values of the graph from left to right. If you do not see an.
A horizontal dashed line crosses the y axis at y 1. 3 2 1 5 4 3 2 3 1 4 5 2 3 5 6 a domain. A vertical dashed line crosses the x axis at x 2.
And then the highest y value or the highest value that f of x obtains in this function definition is 8. Enter your answers using interval notation the x y coordinate plane is given. F of negative 4 is 0.
