Question

The output is three less than the input

Answer 1

Call the output f(x)
Call the input x
f(x) = x - 3

Answer 2

Answer:

$y=x-3$

Step-by-step explanation:

We have been given a description. We are supposed to represent our given description in an equation.

We know that input of a function is x values and it is independent variable. The output is y values and it is dependent on x.

The output is three less than the input. We can represent this information in an equation as:

$\text{Output}=\text{Input}-3$

$y=x-3$

Therefore, our required equation would be $y=x-3$.
