The
negative exponent rule says that when a base has a negative exponent, flip the base onto the other side of the fraction to make it into a positive exponent. For example,

.
Also remember that the
zero exponent rule says that any number raised to zero is 1. For example,
.
Back to the Problem:
To fill out the table, you want to plug in the x-values you're given in the first row into
to get the y-values in order to fill in the second row.
The missing y-values are for when x = -2, x = 0, and x = 2.
Find x = -2. Use the negative exponent rule:

Find x = 0. Use the zero exponent rule:

Find x = 2.
