Where on the Production Possibilities Curve (PPC) is considered EFFICIENT? O A. On the curve
O B. Under the curve
C. Outside the curve
D. Anywhere on the graph

A is efficient, B is not efficient, C is not achievable, D is not correct.

To solve this integral, what you can do is split it up as follows: (1) ∫40(x2−4)dx=∫40(x2)dx−∫40(4)dx. to integrate  4  as an  indefinite integral, a good rule of thumb is  by  an equation below  for  polynomials; . (2) ∫xa=xa+1a+1+c , where a is any number. c denotes some constant that is crucial when doing
