- Begin by entering your name, date, and class in the designated fields at the top of the form. Make sure this information is accurate, as it will be important for identification and grading purposes.
- For the first set of relations, you will see a series of ordered pairs. Represent these relations as a table, graph, and a mapping diagram. Utilize the space provided for each representation.
- Next, identify the domain and range for each relation. Write down the domain (the set of all possible x-values) and the range (the set of all possible y-values) in the designated sections.
- Determine whether each relation is a function by checking if each x-value is paired with only one y-value. Indicate 'Yes' or 'No' in the appropriate field for each relation.
- Provide explanations for your determinations on whether the relation is a function or not in the provided explanation sections.
- After completing all sections, review your answers for accuracy. Once satisfied, you can save your changes, download, print, or share the completed form according to your needs.

What is an example of a relation and a function?
For example, y = x + 3 and y = x2 – 1 are functions because every x-value produces a different y-value. A relation is any set of ordered-pair numbers. In other words, we can define a relation as a bunch of ordered pairs.

What is an example of a relation in math?
A relation is represented either by Roster method or by Set-builder method. Consider an example of two sets A = {9, 16, 25} and B = {5, 4, 3, -3, -4, -5}. The relation is that the elements of A are the square of the elements of B. In set-builder form, R = {(x, y): x is the square of y, x ∈ A and y ∈ B}.

What is a relation in math?
A relation between two sets is a collection of ordered pairs containing one object from each set. If the object x is from the first set and the object y is from the second set, then the objects are said to be related if the ordered pair (x,y) is in the relation.
What is an example of a relation vs function?
For instance, X and Y are the two sets, and 'a' is the object from set X and b is the object from set Y, then we can say that the objects are related to each other if the order pairs (a, b) is to be in relation. Functions- The relation that defines the set of inputs to the set of outputs is called the functions.
How do you determine whether a relation is a function practice?
Identify the input values. Identify the output values. If each input value leads to only one output value, classify the relationship as a function. If any input value leads to two or more outputs, do not classify the relationship as a function.
What is relations and functions?
The relation shows the relationship between INPUT and OUTPUT. Whereas, a function is a relation which derives one OUTPUT for each given INPUT. Note: All functions are relations, but not all relations are functions.
