math help

Answer 1

@Zepdrix I know it's not the 1st one, since that just equals 5

Answer 2

the 2nd one: 2=\[\sqrt{-2-2-5}\]

Answer 3

notice that we have x-2 under the root,
so plugging in anything less than 2 is gonna leave us with a negative under the square root, which is no bueno.

\(\large\rm \sqrt{-5-2}=\sqrt{-7}\)
\(\large\rm \sqrt{-2-2}=\sqrt{-4}\)
\(\large\rm \sqrt{1-2}=\sqrt{-1}\)
We can't take the square root of a negative, these x values will all fail to give us a point for the function.

Answer 4

But x=3 is larger than 2, yay! Try that one :D
