#### Explanation:

Non-linear functions are important because they are used in many real-life applications. For example, parabolas can be used to graph projectile motion. Exponential functions are important because they can be used to graph population growth of bacteria as it multiplies over time. Sinusoidal functions can be used to model the movement of a pendulum or ferris wheel.
