this is a absolut value question:

here is the function y=|squareroot(2-x)-2|+3

and here is the answer but i dont know how to get it

Start with the function 2-x and square root it. Then lower it by 2 units. Anything below the x-axis is flipped due to the absolute value and finally, raise it by 3 units.
