You can put this solution on YOUR website! If y=square root(x)-2, fill in the following table for x=0,1,2,3,4. Round to three decimal places where necessary.
x y
0.sqrt(0)-2 = -2
1.sqrt(1)-2 = -1
2.sqrt(2)-2 = 1.414..-2 = -0.5857..
3. etc

b. explain why no negative values are chosen as values to substitute in for x.
