SUPPORT Class Learning Target
By the end of the period, I will represent a function as a graph with a domain { x } and a range { f(x) }.
I will demonstrate this by completing Four-Square Notes and by solving problems in a pair/group activity.
Teacher Note: Graph paper helpful for this lesson.

5. HW # 3
Make a table of Ordered Pairs and Graph the function.
y = x + 3
domain:
0, 1, 2, 3, 4, 5 x y

6. HW # 5
Make a table of Ordered Pairs and Graph the function.
y = 2x + 2
Choose an appropriate scale for your graph!!
domain:
-2, -1, 0, 1, 3, 7 x y

7. Vertical Line Test
Notes:
The vertical line test is a test to graphically determine if a relation is a function.
To use the vertical line test, draw vertical lines at any point throughout your graph. If the graph intersects the vertical line more than once at any given value of x, the graph is NOT a function. However, if the graph intersects the vertical line no more than once at any given point, it is a function.

8. Storm Check (Think, Write, Discuss, Report)
