Question 1187478
domain are all values of x, which can be 0,1,2,3,4,5,6, or integers [0, 6]
range is the values of y which are between 4 (x=0) and 124 (x=6) or [4, 124]
NOTE: I am using the given f(x), although I wonder if it should be 20x+3, since the base weight is 3 pounds, not 4, unless there is something I don't know about.
