Relation is a function y equals -8?
determine whether each relation is a function y equals -8
What are two ways to determine whether a relation is a function?
Two ways to determine whether the relation is a function is use a mapping diagram or use a vertical line test.
What test is used to determine if a relation is a function?
You can use the vertical line test to determine if a relation is a function. It's pretty simple: if there is any part of the graph where there are more than one of the same x-values for different y-values (ex. (3,2), (3,5), and (3,9)), the relation is not a function
Can you have a function that is not a relation?
No, a function must be a relation although a relation need not be a functions.
Is it true or false that a relation is a special type of function?
No. A relation is not a special type of function.
Which of these data sets represents a function?
Does the graph above show a relation, a function, both a relation and a function, or neither a relation nor a function?
How do you determine if a relation is a function?
A relation is a function if every input has a distinct output.
Relation is a function y equals -8?
determine whether each relation is a function y equals -8

Is the relation a function?
Not every relation is a function. But every function is a relation. Function is just a part of relation.
How do you determine if it's a function?
To determine if a relation is a function, you can use the vertical line test. If a vertical line intersects the graph of the relation at more than one point, then it is not a function. In a function, each input value (x) can only correspond to one output value (y).
Can you have a function that is not a relation?
No, a function must be a relation although a relation need not be a functions.
What is The test to determine if a graph is a function is?
A graph is represents a function if for every value x, there is at most one value of y = f(x).
Is a function always a relation and a relation always a function?
yes.
When does a relation be a function?
A function is a relation whose mapping is a bijection.
Is all relation a function?
Not every relation is a function. A function is type of relation in which every element of its domain maps to only one element in the range. However, every function is a relation.
