1. 1.8: Interpreting Graphs and Functions Unit 1: September 4, 2014

2. Between you and your neighbors, interpret and describe the graph as SPECIFICALLY as you can

3. Did you match these? Positive and negative values x & y intercepts Increasing/Decreasing (Going up/down) Relative Max/Min (Peaks and Valleys) End Behavior Lead Coefficient Direction Symmetry

4. Positive – Negative Values Positive Value – Above the x-axis Negative Value – Under the x-axis

5. Intercepts X-intercept – When the graph Crosses the x-axis. Y=0 Y-intercept – When the graph Crosses the y-axis X=0

6. Increasing/Decreasing Decreasing – Graph is going down Increasing – Graph is going up

7. Relative Maximums/Minimums Relative Min – Graph goes from Decreasing to Increasing Relative Max – Graph goes from Increasing to decreasing

8. End Behavior This graph is an even power Even graphs both go up or both Go down. This graph is an odd power Odd graphs go in opposite directions

9. Lead Coefficient This graph has a positive lead coefficient. The graph ends going up This graph has a negative lead coefficient. The graph ends going down

10. Symmetry

11. Sketch a graph with the characteristics: Has x-intercepts at -5 and 2 Decreasing for x < -2 Increasing Everywhere else
