Given `h(x)=sqrt(x)-2` :

`x=0 ==> h(0)=sqrt(0)-2=-2`

`x=1 ==> h(1)=sqrt(1)-2=-1`

`x=4 ==> h(4)=sqrt(4)-2=0`

`x=9 ==>h(9)=sqrt(9)-2=1`

Now y=h(x) so we have:

x   h(x)  y
-----------
0     -2   -2
1     -1   -1
4      0     0
9      1     1

Set up a x/y table, placing the given x-values as your inputs. Plug each x-value into the radical expression and simplify completely for the output, your y. 

x              h(x)              y 

0             sqrt (0) - 2      -2

1             sqrt (1) - 2      -1

4             sqrt (4) - 2       0

9             sqrt (9) - 2       1
