Step 1: We have the following function:
The revenue earned from selling cars as a function of price
Step 2: We place revenue on the x-axis and price on the y -axis, therefore, the higher the price of a car is, the more revenue we wil get from seliing that car.
Step 3: The function that represents the function described on Step 2 it is B. There is a line that is increasing x and y values because as we explained, the higher the price is, the more revenue we will make.
