Math 1314 Lesson 21 Area Between Two Curves Two advertising agencies are competing for a major client. The rate of change of the client’s revenues using Agency A’s ad campaign is approximated by f ( x ) below. The rate of change of the client’s revenues using Agency B’s ad campaign is approximated by g ( x ) below. In both cases, x represents the amount spent on advertising in thousands of dollars. In each case, total revenue is the area under the curve given in thousands of dollars. Agency A Agency B This graph shows the relationship between the two revenue functions. We see that one function is above the other. The area between the two functions represents the projected additional revenue that would be realized by using Agency B’s ad campaign.
