Is a function always a relation and a relation always a function?
yes.
How do you determine if a relation is a function?
A relation is a function if every input has a distinct output.
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.
If a set of ordered pairs is not a relation can the set still be a function?
If a set of ordered pairs is not a relation, the set can still be 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 does you know that relation is a function?
One way is to try the vertical line test on a graph!
How do you determine if a relation is a function?
A relation is a function if every input has a distinct output.
What is the difference between function and a relation?
Good question. A relation is simply that; any x-value to create any y-value. A function, however, cannot be defined for multiple values of x. In other words, for a relation to be a function, it must have singular values for all x within its domain.
Is it true or false that a relation is a special type of function?
No. A relation is not a special type of function.
Is every relation a function?
No, not every relation is a function. In order for a relation to be a function, each input value must map to exactly one output value. If any input value maps to multiple output values, the relation is not a function.
