Example Problem
2
1. Create a table with 3 points
x y
-‐2 2.5
0 -‐1.5
2 -‐4.5
2. Label the slope triangles on the graph
3. Write an equa/on using the graphic organizer. 4. Is the graph a func/on? Jus/fy your answer. This graph is a func.on because it passes the ver.cal line test. 5. What type of correla/on is present? Is it increasing or decreasing from leL to right? Nega.ve correla.on, the graph is decreasing from le: to right. 6. Is the graph con/nuous or discrete? Jus/fy your answer. The graph is con.nuous because the points are connected by a line. 7. What is the speed of the graph? Is it more steep or less steep? Fast or slow? The graph is more steep, it is decreasing fast. 8. Write the Domain and Range in interval nota/on. D: (-‐2, 2] start at the most nega.ve endpointàposi.ve endpoint on the x-‐axis. R: [-‐4.5,1.5) start at the most nega.ve endpointàposi.ve endpoint on the y-‐axis.
