The difference between relation and function is described

<em><u>Solution:</u></em>

Let us first understand about relation and function

A relation is a set of inputs and outputs that are related in some way.

When each input in a relation has exactly one output, the relation is said to be a function.

To determine if a relation is a function, we make sure that no input has more than one output

Every function is a relation ,but every relation doesn't represent a function

<em><u>Example:</u></em>

R = {(2, x), (9, y), (2, z)}  

It is not function as “2” is input for both x and z

F = {(2, x), (9, y), (5, x)} is a function because all the first elements are different.

<em><u>Differences:</u></em>

<em><u>Relation:</u></em>

  • A relation is a relationship between sets of values
  • A relation is denoted by “R”
  • Every relation is not a function.

<em><u>Functions:</u></em>

  • A function is a relation in which there is only one output for each input.
  • A function is denoted by “F” or “f”
  • Every function is a relation.

A number a decreased by 7 is 2.
umka21 [38]

Answer:

9

Step-by-step explanation:

Let's first convert this to numbers. When a number is decreased by a certain amount, that is the same as saying that something is subtracted from it. Therefore:

a-7=2

Add 7 to both sides:

a-7+7=2+7

a=9

Hope this helps!
