Hello! May someone ensure my understand of antiderviates and derviates.
A is true because a constant (which can be of any value ) is involved when you do the 'anti-derivative'
Example Anti derivative x2 +3 x^2 +12 x^2 +19
all have derivative of 2x
so, in other words , the 'anti-derivative' of 2x can be any of the red equations (or more)
