Write a function rule for the table.

x ƒ (x)

3 - 1

4 0

5 1

6 2

Step-by-step explanation:

When one variable depends on another variable according to a rule it is known as function:

For example if you want an output of 2 and the input value is 4. Then you will subtract 4 from x

We have to find x f (x).

x f (x) = ?

f (x) = x-4

Now input value is: x = 3

x f (x)

3 (x-4)

3 (3-4)

3 - 1

Now x = 4

x f (x)

4 (x-4)

4 (4-4)

4 0

Now x=5

x f (x)

5 (x-4)

5 (5-4)

5 1

Now x=6

x f (x)

6 (x-4)

6 (6-4)

6 2 ...
