This is Vector Calculus. Please answer thoroughly with clear answers and explanations. This is a 4 part question split into two different posts. PLEASE ONLY ANSWER PARTS A AND B. Thank you

(c) Part of the parabola \( y = 2(x+1)^2 \) from the point \( (0, 2) \) to the point \( (-1, 0) \).

(d) Counterclockwise around the perimeter of a triangle of area 3.  
Hint: If the curve \( C \) is a finite union of the smooth curves \( C_1, \cdots , C_n \) joining end to end then

\[
\int_C f \, ds = \sum_{i=1}^n \int_{C_i} f \, ds.

**Exercise 2: Evaluating Line Integrals**

Evaluate the line integral of the function \( f(x, y) = -y + x \) along the following paths in the \( xy \)-plane:

(a) **Straight Line Path:** From the point \( (0, 1) \) to the point \( (1, 2) \).

(b) **Circular Path:** Move counterclockwise around a circle with a radius of 4, centered at the origin. Start the path from the point \( (4, 0) \) and end at the point \( (0, -4) \).
