To find the general antiderivative of ( f(x) = \frac{1}{2} + \frac{3}{4}x^2 - \frac{4}{5}x^3 ), integrate each term separately with respect to ( x ):

- The antiderivative of ( \frac{1}{2} ) with respect to ( x ) is ( \frac{1}{2}x ).
- The antiderivative of ( \frac{3}{4}x^2 ) with respect to ( x ) is ( \frac{1}{4}x^3 ).
- The antiderivative of ( -\frac{4}{5}x^3 ) with respect to ( x ) is ( -\frac{1}{5}x^4 ).

Combine these antiderivatives to get the general antiderivative of ( f(x) ):

[ F(x) = \frac{1}{2}x + \frac{1}{4}x^3 - \frac{1}{5}x^4 + C ]

where ( C ) is the constant of integration.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
