Chapter 13.4, Problem 2CP

(a)

To determine

Whether the integral expression $CS={\displaystyle \underset{0}{\overset{x_1}{\int }}f\left(x\right)dx-p_1{x}_1}$ is true or false for a supply function $p=f\left(x\right)$ and the demand function is $p=g\left(x\right)$.

(b)

To determine

Whether the integral expression $PS={\displaystyle \underset{0}{\overset{x_1}{\int }}f\left(x\right)dx-p_1{x}_1}$ is true or false for a supply function $p=f\left(x\right)$ and the demand function is $p=g\left(x\right)$.
