Question

Given the functions f(x) = x(x-2) and g(x) = 2x + 4, which is the corresponding table?

Answer 1

see below

Explanation:

One of the ways you can tell is that g(x) is always even. Only one table has that.

g(x) = 2(x +2)

g(x) has a factor of 2 in every result, so cannot be odd for any integer x.
