You don't make it clear, but I assume you just want help filling in the table.

The first x value is -2, so

y=-x%5E2%2B1
y=-%28-2%29%5E2%2B1
y=-%284%29%2B1=-3

So -3 is your first y value.

Just repeat this process of substituting the table value for x into the equation and then performing the necessary arithmetic to find the value of y.
