In order to find the y-values, we need to substitute the x-values into the given function. That is, for x=-2, we have

So, the first row of our table is -2 10.
Similarly, by substituting x=0 into the function, we have

By substituting x=2 into our function, we have

and finally, by substituting x=4 into our function, we get

Therefore, the table is:
