Is the number of students on a field trip a function of the number of buses used? Explain.
Yes, the number of students on a field trip can be considered as a function of the number of buses used. A function is a relationship where each input (independent variable) corresponds to exactly one output (dependent variable). In this case, the number of buses used is the input, and the number of students on the field trip is the output.
When more buses are used, it typically allows for more students to be accommodated on the field trip. As long as each bus can carry a certain number of students, the number of students on the field trip increases as the number of buses used increases. This one-to-one correspondence between the number of buses and the number of students on the field trip fulfills the criteria for a function.
