Linear Vs Exponential

Front

What is the main difference between linear and exponential functions?

Back

Linear functions have a constant rate of change, while exponential functions have a variable rate of change that increases rapidly.

Front

Define a linear function.

Back

A linear function is a function that graphs to a straight line and has a constant rate of change.
