Question

Write a function rule for the table

Answer 1

x - y = 4, this is the function.

Explanation:

See the table attached.

The value of f(x) changes uniformly with corresponding values of x and hence the function f(x) will be linear.

Now, take any two ordered pairs of to get the equation of the function.

Let those are (4,0) and (5,1).

Therefore, the equation will be
`(y - 1)/(1 - 0) = (x - 5)/(5 - 4)`

⇒ y - 1 = x - 5

⇒ x - y = 4.

So, this is the function.
