If an operator reduces the bus fare by $0.25 for every additional passenger he gets, he has to figure out the point to stop doing that to remain profitable. Give an example of a real life situation where it is important that the coding functions be one-to-one. The function is the sum of "n" plus "m," the domain is all real numbers and the output is also all real numbers. Let x represent the number of hours and y represent the amount charged for x hours. • A function f is (strictly) decreasing if ∀x 1,∀x 2, x 1 < x 2 implies f(x 1) > f(x 2). The function is the sum of "n" plus "m," the domain is all real numbers and the output is also all real numbers. So, we need to find a way to represent the cost of this bus ride using variables, constants, and sums. Notice that if you graph the x and y values you would get the following ordered pairs: day 1 (1, 5), day 2 (2, 10), day 3 (3, 15), and day 5 (4, 20).
