Mr. witherspoon runs a publishing house that publishing house that publishes a financial magazine. the graph depicts the number of copies sold last year. arrange the sections of the graphed function in order of their steepness, starting with the section that increases the slowest and ending with the section that increases the quickest.

For this case, the first thing we must do is observe that the graph is composed of the following functions:
 Function A
 Function B
 Function C
 Function D
 Function E
 From here, we must observe the function that has the least slope until the function that has the highest slope.
 Since the functions are linear, then we must observe the inclination of the functions:
 Function E
 Function B
 Function C
 Function A
 Function D
 
 E, B, C, A, D

The correct answer is 7
