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?

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
