## MAT 116 Week 5 DQs

**MAT116 Week 5 Discussion Question 1**

Post your response to the following:

What similarities and differences do you see between functions and linear equations studied in Ch. 3?

Are all linear equations functions? Is there an instance when a linear equation is not a function? Support your answer.

Create an equation of a nonlinear function and provide two inputs for your classmates to evaluate.

Find examples that support or refute your classmates answers to the discussion question. Provide additional similarities and differences between functions and linear equations.

Challenge your classmates by providing more intricate examples of nonlinear functions for them to solve.

**MAT116 Week 5 Discussion Question 2**

Post your response to the following:

What is the difference between domain and range? Describe a real-life situation that

could be modeled by a function.

Provide feedback about your classmates answers.

Describe the values for *x*that may not be appropriate values even when they are defined by your classmates function. A function could, for example, indicate the amount of bone strength (*y*) in a living human body over time in years (*x*). It would not make sense to look at negative years, because the person would not yet be born. Likewise, looking beyond 100 years might not make sense, as many people do not live to be 100.
