Question

What is the rule for a function with inputs, 0,1,3,4 and outputs
4,3,1,0?

Answer 1

Answer:
`y=4-x`

Explanation:

• A function is a relation in which every input associates with an unique output.

Let x denotes the input values and y denotes the output values.

As per the given we have the following table :

x y

0 4

1 3

3 1

4 0

We can see that the sum of each x and corresponding y is 4.

i.e. x+y= 4

Since we write the function in terms of independent variable (x) to show dependent variable (y).

So our function becomes ,
`y=4-x`

So the rule for a function with inputs, 0,1,3,4 and outputs 4,3,1,0 would be

`y=4-x`
