Using to Model the Height of a Dropped Ball
To evaluate the height of a falling object using a polynomial function, substitute the given time into the equation. For example, the function models the height in feet of a ball seconds after being dropped from a -foot bridge. To find the ball's height after seconds, evaluate the function at . Substitute for to obtain . First, square the to get . Next, multiply by to get . Finally, add and to arrive at . Therefore, the height of the ball after seconds is feet.

Procedural Steps for Evaluating Models
An operations manager at a logistics company uses polynomial functions to predict fuel consumption based on vehicle weight. To analyze these models correctly, the manager must understand the specific components of the mathematical process. Match each term with the description of its role in this analysis.
A logistics company uses a polynomial function to model fuel consumption based on vehicle speed. True or False: To evaluate this function for a specific speed, that value must be substituted for the variable in every term of the polynomial expression before the order of operations is used to simplify the result.
