nonlinear function. Explain. x 0 5 1 1
0 5 y 2 1 1 8 0 6 2 Nonlinear functions are ​
functions whose rate of change are not constant. Therefore, their graphs are not straight lines. Linear functions are functions that have straight lines in their graphs. The constant rate of change is constant. Example 3c: Page 329 Example 4d: Page 330 Summary: Tickets to the school dance Numbe 1 2 3 of cost $5 per r tickets student. Are the Sold tickets sales a Ticket $5 $10 $15 linear function Sales of the number of tickets sold? A square has a side length of s inches. The perimeter of the square is a function of the side length. Does this situation represent a linear or nonlinear function? Explain
