Question 394361: This is a discussion question in my class. I have seen how a few other students have written an answer for a linear function, but I am having trouble with choosing a real life function and actually writing out the process. I am trying to grasp it- need help. Thank you.

In a linear function, the rate of change is constant. In a non-linear function, the rate change is not constant. (It may be predictable, or it may not be - but the rate of change is not a constant - a number.) A piecewise function is a function that is described in different pieces over it's domain. Describe either real life situation that could be modeled be either a linear, a non-linear function, or a piecewise function.
Explain why the model is linear, non-linear, or piecewise?
I need to make sure that I describe what is the input variable and what is the output variable in my model.
