(10 marks) 1. Domain of a Function y= f(x). (5 marks) It is the set of all possible values of x . 2. Market Equilibrium. (5 marks) Market equilibrium exists if there is a price at which the quantity supplied equals the quantity demanded. Therefore market equilibrium occurs when (Q2) Identify which of the following underlined statement is “True” and which is “False” and rewrite the exact underlined statement for the false ones. (10 marks) 1. If the quantity supplied of a certain product is given by the following function: where q s is the quantity supplied in units and p is the selling price in dollars, then we can say that “ For every increase in the selling price by 3 $, the quantity supplied decreases by 100$ “.(5 marks) False increases by 60 units 2.

Specifically, it was found that when the company produces 150 cameras per week, a total cost of 38400$ is incurred; when the production increase to 250 cameras per week, the total cost reaches 63400$. a) Use the above information to obtain a linear cost equation of the form: where C is the weekly total cost in dollars and x is the number of cameras produced per week. (15 marks) (150, 38400) & (250, 63400) Slope ( 150, 38400) b) From the above relation determine the marginal cost and interpret its meaning.
