Answer:

The value would be 14.

Step-by-step explanation:

To find this, we first write out the equation as they request (f - g).

f(x) - g(x)

3x^2 + 1 - (1 - x)

Now we simplify.

3x^2 + 1 - (1 - x)

3x^2 + 1 - 1  + x

3x^2 + x

Now that we have this, put 2 in for x.

3(2)^2 + 2

3(4) + 2

12 + 2

14
