Any mapping in which
Not every relation is a function. But every function is a relation. Function is just a part of relation.
A relation is a function if each input (or domain value) is associated with exactly one output (or range value). To determine this, you can check if any input value appears more than once in the relation; if it does, the relation is not a function. Additionally, in a graph, a relation is a function if it passes the vertical line test—if any vertical line intersects the graph at more than one point, it is not a function.
A function is a relation whose mapping is a bijection.
No. A relation is not a special type of function.
A graph can represent either a relation or a function, depending on the nature of the relationship between the variables depicted. A relation is simply a set of ordered pairs, while a function is a specific type of relation where each input (or x-value) is associated with exactly one output (or y-value). To determine if a graph represents a function, the vertical line test can be applied: if any vertical line intersects the graph at more than one point, it is not a function.
A relation is a function if every input has a distinct output.
determine whether each relation is a function y equals -8
Two ways to determine whether the relation is a function is use a mapping diagram or use a vertical line test.
If the function is a straight line equation that passes through the graph once, then that's a function, anything on a graph is a relation!
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

No, a function must be a relation although a relation need not be a functions.
Does the graph above show a relation, a function, both a relation and a function, or neither a relation nor a function?
A function is a relation whose mapping is a bijection.
yes.
