We have to find the missing parts of the table for the function:

This will be done by replacing each x-value onto the function.
For x=-2
We obtain:

This means that for x=-2, the value of y is 49.
For x=0
As every number (except 0) elevated to 0 is 1, we have

This means that for x=0, the value of y is 1.
For x=2

This means that for x=2, the value of y is 1/49.
