1. Describe the graph and critical values and characteristics of f(x) = -(2)^x +1
2. What is the solution set? What steps did you take to determine the solution set?
x^2+9x+20/x^2-x-20 ≥ 0
3. How do you use the Unit Circle to find the cos 210° in exact form? No decimals.
4. After the parent cosine functions are:
Vertically compressed by one half
Horizontally stretched to a period of 4pi
Vertical shift of -1
A phase shift of pi units left

Where does the new function:
4a. cross the y-axis
4b. what is the maximum?
4c. What is the minimum?
