Program Explanation Given information: The pollutant concentration is c ( t ) = 10 L / m 3 , average depth of water is 2 meters the liquid pollutant flows at the rate of 2 × 10 5 m 3 per month. Explanation: The mount of solute x ( t ) satisfies the below differential equation. d x d t = r i c i − r o V x ....... (1) Here, r i , c i , r o are constants and V is the volume of the solution. The value of r i in millions of liters per second is calculated as, r i = 200 × 10 3 m 3 / month = 0.2 × 10 6 m 3 / month = 1 5 million liters The rate of inflow and outflow is same, so r o = 1 5 and the value of volume in millions of cubic meters is 2 . Substitute 1 5 , r i and 1 5 for r o , 10 for c i and 2 for V in equation (1). d x d t = 1 5 ⋅ 10 − 1 5 2 x d x d t = 2 − 1 10 x d x d t + 1 10 x = 2 The above equation is a linear first-order equation and its solution is calculated as, x e 1 10 ∫ d t = 2 ∫ e 1 10 ∫ d t d t x e t 10 = 2 ∫ e t 10 d t = 2 1 10 e t 10 + C = 20 e t 10 + C Simplify the above equation. x = 20 + C e − t 10

2. (5 points) Let f(x) = = - - - x² − 3x+7. Find the local minimum and maximum point(s) of f(x), and write them in the form (a, b), specifying whether each point is a minimum or maximum. Coordinates should be kept in fractions. Additionally, provide in your answer if f(x) has an absolute minimum or maximum over its entire domain with their corresponding values. Otherwise, state that there is no absolute maximum or minimum. As a reminder, ∞ and -∞ are not considered absolute maxima and minima respectively.
