Question

A function adds 5 to a number, divides the sum by 2, and then subtracts

3 from the quotient. Which of the following could be the function?

Answer 1

`f(x) = (x+5)/(2) - 3`

Explanation

Let the unknown number be x

If the function adds 5 to the number, then;

f(x) = x + 5

If it is divide by 2;

f(x) = x+5/2

If it is then subtracted from 3;

`f(x) = (x+5)/(2) - 3`

Hence the required function will be
`f(x) = (x+5)/(2) - 3`
