Lesson 5: Applications
Duration of Days: 2
Lesson Objective
Students will be able to interpret the meaning of a function given as a graph for a real world application and provide the parameters of a function.
Find the domain and range of a function.
Find the output given the input
Provide the units of the input and output.
1. HSF-IF.A.1
Understand that a function from one set (called the domain) to another set (called the range) assigns to each element of the domain exactly one element of
the range. If f is a function and x is an element of its domain, then f(x) denotes the output of f corresponding to the input x.
A function is a relationship between input and output in which each input value has exactly one output. The set of input values is the domain of the function and the set of output values is the range of the function.
The distance a car travels from when the brakes are applied to the car's complete stop is the stopping distance. This includes time for the driver to react. The faster a car is traveling the longer the stopping distance. The stopping distance is a function of the speed of the car.
