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?
HELP ASAP please

idk what the heck he answer is, i’m just putting this here so i finish my account

it would not be increasing by nothing that i can see probably by 25 percent that is all i can sat\y for now if i have any thing else to say i will edit this.

step-by-step explanation:

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6
