Let A 1 4 9 16 and B 1 2 3 4 5 6. We say the output is a function of the input The input values make up the domain and the output values make up the range. Relation- In maths the relation is defined as the collection of ordered pairs which contains an object from one set to the other set. If there is then it is NOT a function. Domain 1 2 3 4 5 Range 1 3 5 Co domain 1 3 5 7 9.

If an x value has more than one y-value associate with it — for example in the relation 4 1 42 the x-value of 4 has a y-value of 1 and 2 so this set of ordered pairs is not a function.

How can you tell if a relation is a function. Youve seen that you sort of flip the original function over the line y x to get the inverse. Then test to see if each element in the domain is matched with exactly one element in the range. I Domain of R 1 2 3 4 5 Set X.

How do you figure out if a relation is a function. So the above relation is not a function. Hence it is not a function.

Hope that answered any of your stated s and to-be s. One can determine if a relation is a function by graphing the relation drawing a vertical line on the graph and then checking whether the line crosses the graph at more than one point. If the line crosses the graph only once the relation is a function.

I have the domain as 012 and the set i think is 031122 How can i tell that a relation or set or whatever is a function. Definition of Relation and Function in Maths. States that if a vertical line intersects the graph of the relation more than once then the relation is a NOT a function.

You could set up the relation as a table of ordered pairs. A WAY easier and faster way to know if it is a function is to see if there are two of the same x-intercept which make a vertical line. And thanks to the Internet its easier than ever to follow in their footsteps or just finish your homework or study for that next big test.

For the element 2 in set X there two images 3 and 1 in Y. What is a function. Then test to see if each element in the domain is matched with exactly one element in the range.

Ii Every element in X has image in Y. You could set up the relation as a table of ordered pairs. Function A function is a relation in which each possible input value leads to exactly one output value.

If so you have a function. The student is expected to gather and record data use data sets to determine functional relationships between quantities. Sorry if that doesnt though I try.

Is a way to determine if a relation is a function. There is a quick way to tell before going to the trouble of finding the inverse whether the inverse will also be a function.
