Is a function always a relation and a relation always a function?
yes.
How do you know if a relation is a function?
relation and function are number that combine with number and neqative number to .
How can you determine that a set of ordered pairs are a graph table diagram equation a function or mere relation?
In general you cannot. Any set of ordered pairs can be a graph, a table, a diagram or relation. Any set of ordered pairs that is one-to-one or many-to-one can be an equation, function.
Why is relation does not function at all times?
Because a function has additional restrictions, which the relation may, or may not, satisfy.
Why all functions relation?
Function is a special case of relation. It means function is a relation but all relations are not functions. Therefore all functions are relations.
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.
How do you determine if a relation represents a function?
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!
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
Is the relation a function?
Not every relation is a function. But every function is a relation. Function is just a part of relation.
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.
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?
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.
A relation is a special type of function?
No. A relation is not a special type of function.
How will you determine if a graph is a function or a mere relation?
You use the "vertical line test". If anywhere you can draw a vertical line that goes through two points of the graph, the relation is not a function; otherwise, it is a function. This is just another way of saying that in a function for every x value (input) there is AT MOST one y value (output).
