1. I can…
…Interpret graphs of functions.
…Draw graphs of functions.

2. Function Output depends on input
There is exactly one output for every input

3. A functions is graphed using a coordinate plane:
x- coordinate
y- coordinate

4. Independent vs. Dependent variables
Distance a person runs over time
Profit made when you raise or lower the selling price
Average price of gasoline rises throughout the year
Height and age

5. Typically independent is on the x-axis and dependent is on the y-axis
Any measure of time (seconds, minutes, days, years, etc.) is almost always independent.

8. Continuous Function: Graph is a smooth curve or a line (can trace without picking up your pencil)
Discrete Function: Graph with points that are not connected

9. 1. Make a table to represent the total cost of buying 1 to 5 pairs of earrings.
2. Independent Variable:
Dependent Variable:
3. Write the data as set of ordered pairs:
4. Graph the data.
5. Domain:
