Question

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

Answer 1

Answer:

$f(x) = \frac{x+5}{2} - 3$

Step-by-step 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;

$f(x) = \frac{x+5}{2} - 3$

Hence the required function will be $f(x) = \frac{x+5}{2} - 3$
