Precalculus - Chapter 1 - Functions and Changes Include Workshop Cover Sheets

1. Sketch the following functions: (Do Not Submit Sketch - you may attach sketch for your reference only)
2. Clear identify the regions of the graphs where the functions increasing or decreasing
3. Have slopes = 0
4. Identify where the functions crosses the y-axis (x = 0) and y-axis (or y-intercept, y = 0).
5. Determine the value of the function at x = 5 and the slope between x = ½ and x = 1.

Function Region(s) Increasing Region(s) Decreasing Zero Slope x-intercept(s) y-intercept y when x = 5 Slope between
x= ½ & 1
