In 2005, the shabelle river in somalia rose an estimated 5.25 inches every hour for 15 hours. the increase in water level is represented by the function f(x) = 5.25x, where x is the number of hours. graph the function and give its domain and range.

3 6 9 12 15. These numbers will be your domain and also what you plug in for x because it fits on the graph.

so your equation for all of these would be this:

f(x)=5.25 (x) 

so

f(3)=5.25 (3) 
15.75

f(6)=5.25 (6) 
31.5

f(9)=5.25 (9)
 47.25

f(12)=5.25 (12) 
63

f(15)=5.25 (15) 
3.75
