2.) a newspaper started an online version of its paper 14 years ago. In a recent presentation to stockholders, the lead marketing executive states that the revenues for online ads have more than doubled that of the revenues for printed ads since starting the online version of the paper. Use the graph below to justify the lead executive statement in to determine the approximate year that the to ad revenues were equal

3.) Two Ocean beaches are being affected by erosion. The table shows the width, in feet, of each beach at high tide measured where 1995 is represented by year 0.

(Chart in pic)

A. Describe the patterns shown by the erosion data measurements shown for each of the beaches in the table.
B. Between what years will the beaches have approximately the same width?
C. Assuming these rates remain constant, what can you do to get a better approximation of when two beaches will have the same width?
