You need to evaluate the most antiderivative of the function, such that:

`int f(x) dx = F(x) + c`

`int ((1/2)x^2 - 2x + 6) dx = int(1/2)x^2 dx - int 2xdx+ int 6 dx`

`int ((1/2)x^2 - 2x + 6) dx = (1/6)x^3 - x^2 + 6x + c`

Hence, evaluating the most antiderivative of the function yields ` F(x) = (1/6)x^3 - x^2 + 6x + c.`
