What is the difference between a relation
taurus [48]

Answer:

Not all relationships are functions, but all functions are also relationships

Step-by-step explanation:

A relationship is a correspondence between two sets of values.

A relationship assigns values from an output set called range to a set and input called a domain.

On the other hand, a relation is a function if and only if there is only one value of the output set (Range) assigning to each value of the input set (Domain).

In other words, if an input value x_1 is assigned two or more output values y_1, y_2, y_3 .. then the relationship is not a function. This means that <em>not all relationships are functions</em>.

y=\±\sqrt{x} +3   is a relation but it is not a function.

because when x = 4 then y = 1 and y = 5.

Not all relationships are functions, but all functions are also relationships
