*this is goes along with the answer to number 3* After the parent cosine functions is:
Vertically compressed by one half
Horizontally stretched to a period of 4pie
Vertical shift of -1
And phase shift of pie units left

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

the answer is (-4,-4)

hope this ! : d

no idea

step-by-step explanation:

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5

-3.5 degrees per hour

step-by-step explanation:

find the unit rate:

-12   1/4 degrees           12.25 degrees

= - = -3.5 degrees per hour

      3   1/2 hours               3.5 hours
