Answer 1

Answer:
`f(x)=3x`

Explanation:

It is important to remember that the input values are the values of
`x` and the output values are the values of
`y` (
`f(x)=y`).

Now, in order to solve the exercise you must analize the table provided. You can observe that each output value is obtained by multiplying the corresponding input value by 3:

`3*2=6\\3*3=9\\3*4=12\\3*5=15`

Therefore, knowing this, you can determine that the function rule for the given table is:

`f(x)=3x`
