The domain of the function 1/2x is {0, 2, 4}. What is the range of the function?
Use the function to find the image of each point in the domain. The set of values that you get will be the range. If the function is well behaved, you will not have to try each and every value in the domain.
To find the Domain and range when given a graph is to take the x-endpoints and to y-endpoint. You know that Domain is your input and range your output. so to find the function when given the graph you simply look at your plot points and use yout domain and range. like so: Say these where your plot points (0,4) and (9,6) You know your domain is {0,9} and it would be written like so: 0<x<9 then noticing your range is {4,6} and it would be written like so: 4<y<6
The domain is a subset of the values for which the function is defined. The range is the set of values that the function takes as the argument of the function takes all the values in the domain.
The range of a function is the set of all of the possible values that it can take on as an output value. You find the range by inspecting the function and seeing first what the domain is, and then what the range would be for that domain. The domain, then, is the set of all of the possible values that it can take on as an input value.
Describe how to find the domain and range of a relation given by a set of ordered pairs.
Find the range of a function by substituting the highest domain possible and the lowest domain possible into the function. There, you will find the highest and lowest range. Then, you should check all the possible cases in the function where a number could be divided by 0 or a negative number could be square rooted. Remove these numbers from the range. A good way to check to see if you have the correct range is to graph the function (within the domain, of course).
i dont know, but you can find it at purplemath.com
You need to know the domain in order to find the range.
how don you find write the domain of a function
Find the maximum and minimum values that the function can take over all the values in the domain for the input. The range is the maximum minus the minimum.
Find all possible "x" and "y" values for domain and range. Then put it in inequality form. For example the domain and range for the equation 2x-3/x-5 would be: Domain: All Reals; x>5 Range: All Reals
To find the range of the function ( f(x) = -10x ) for the given domain (-4, -2, 0, 2, 4), we can evaluate the function at each point in the domain. For ( x = -4 ), ( f(-4) = 40 ) For ( x = -2 ), ( f(-2) = 20 ) For ( x = 0 ), ( f(0) = 0 ) For ( x = 2 ), ( f(2) = -20 ) For ( x = 4 ), ( f(4) = -40 ) Thus, the range of the function is ([-40, 40]).
