Question

G(x) + (-g(x)) =a. 2g(x)b. -2g(x)c. 0

Answer 1

Let's think of g(x) as a variable, it could be called for example y, then by replacing y for g(x), then we get:

y + (-y)

Since adding -y is equivalent to subtracting y, then we can rewrite the expression like this:

y-y

which equals 0, y - y = 0

Then, the correct answer is option c
