Question

At what input value will the function f(x) = -x - 2 + 2 begin to have real outputs?

Answer 1

The function will begin to have real output when the input value is 2

How to determine the input value?

The function is given as:

$f(x) = -\sqrt{x - 2} + 2$

Set the radical greater than or equal to 0

$x - 2 \ge 0$

Add 2 to both sides

$x \ge 2$

This represents the domian

Hence, the function will begin to have real output when the input value is 2
