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 linear function and provide two inputs for your classmates to evaluate.

Find examples that support or refute your classmatesâ€™ 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.
