I am trying to solve these set of true and false antiderivatives but cant seem to get the set right.. Can anyone point out where my concept went wrong?

The questions is in the link

1. F(x)+C, so that's false

2. derivative = differentiate, true

*3. F-G is anti-derivative of f-g. this one should be true. F-G can be split into 2 separate anti-derivatives, under the (addition/subtraction rule?)

4. F'(x) = f(x) true. F is anti-derivative, and ' is derivative, so it just goes back to f

5. f'(x) = F(x) false

6. false, C is any arbitrary constant. making unlimited number of antiderivative
