It's time to sharpen the pencil and do some arithmetic!

x     f(x) = 2.5x - 10.5       g(x) = 64(0.5x)
2    f(x) = 2.5(2)-10.5         g(x) = 64(0.5*2)
       f(x) = 5-10.5 = -5.5     g(x) = 64(1) = 64
now repeat for x = 3, 4, 5, 6

heres my one of my other questions 

3.	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’s statement and to determine the approximate year that the two ad revenues were equal.
