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!
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.
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.
No. A relation is not a special type of function.
Does the graph above show a relation, a function, both a relation and a function, or neither a relation nor a function?
A relation is a function if every input has a distinct output.

Two ways to determine whether the relation is a function is use a mapping diagram or use a vertical line test.
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.
To determine the direction of a vector, you can use trigonometry. Find the angle the vector makes with the positive x-axis using the arctangent function. This angle represents the direction of the vector in relation to the x-axis.

This statement is incorrect. A mapping diagram can represent both functions and relations. A relation is any set of ordered pairs, while a function is a specific type of relation where each input (or domain element) is associated with exactly one output (or range element). In a mapping diagram, if each input has a single output, it represents a function; if an input has multiple outputs, it represents a relation that is not a function.
To determine if a relation is a function, you can use the "vertical line test." If any vertical line drawn on the graph of the relation intersects the graph at more than one point, then the relation is not a function. Additionally, in a set of ordered pairs, a relation is a function if each input (or x-value) corresponds to exactly one output (or y-value).
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.
To determine if a relation is a function, check whether each input (or x-value) corresponds to exactly one output (or y-value). This can be done by examining ordered pairs or a graph: if any x-value maps to multiple y-values, the relation is not a function. In a graph, if a vertical line intersects the curve more than once, the relation fails the vertical line test and is not a function.
