Answer:

a) True

Step-by-step explanation:

To prove that g(x) = o(f(x)), we need to show that for any positive constant c, there exists a positive constant k such that for all x > k, |g(x)| < c|f(x)|.

Let's assume c = 1 and find k such that for all x > k, |g(x)| < |f(x)|.

Since f(x) = 3x - 7 and g(x) = x, we have:

|g(x)| = |x|, and

|f(x)| = |3x - 7|.

Now, let's choose k = 7. For any x > k, we can see that:

|g(x)| = |x| < |3x - 7| = |f(x)|.

Therefore, g(x) = o(f(x)).
