For this case we have a function of the form
where:

We simplify eliminating common terms of the numerator and denominator:

We must find the values of the function when:
x = {-2, 0, 3, 5, 7}
So, we have:
For
:

For

For
:

Thus, the values of the function are:
y = {-2, 0, 3, 5, 7}
Answer:
y = {-2, 0, 3, 5, 7}
