Question 755987
y = square root of 16 minus x squared

I am asuming that it is square root of (16-x^2). As in all under the square root sign. With that being said, let's split it up first to this:


y= square root of 16 + square root of -x^2


y= 4 + -x


y= 4-x


Hope this helps! If not feel free to ask again.
