Question 1 \text { Evaluate } \int_{C} \mathbf{v} \cdot d \mathbf{r} \text { in the case that } \mathbf{v}=(x z+x, \quad y-z, \quad 4 x) and C is the straight

line from (2 -1 -1) to (-2 -3 2). Enter only the final answer in exact form (no decimal approximations). \int_{C} \mathbf{v} \cdot d \mathbf{r}=
