Bell Ringer:What is one possible graph of the relationship between the total cost and the number of pictures you print.


What is the graph of the function rule:

y = -2x + 1?


Step 1: Make a table of Values

x y = -2x + 1 (x, y)

Step 2: Graph the Ordered Pairs:

Step 3: Connect the points with a line to represent all

solutions:


Key Concepts:

Continuous Graph:

A continuous graph is a graph that is unbroken


Discrete Graph:A discrete graph is composed of distinct, isolated point


A local cheese maker is making cheddar cheese to sell at a farmer’s market. The amount of milk used to make the cheese and the price at which he sells the chees are shown below


1. Write a function for each situation

2. Make a table of values for each situation.

3. Graph each function4. Is the graph continuous

or discrete?


• 1 gallon of milk makes 16 oz of cheddar cheese• Each wheel of cheese costs $9

A certain function fits the following description:

As the value of x increases by 1 each time, the value of y continually decreases by a smaller amount each time, and never reaches a value as low as 1.

1. Is this function a linear or nonlinear? 2. Explain your reasoning?
