Answer:
It has amplitude of 
.
It is a horizontal shift of the parent function 
units left.
Step-by-step explanation:
We have the function, 
.
It is clear that the parent function is 
.
So, we see that,
The amplitude of the function f(x) is , which gives, 
.
Also, g(x) is translated units to the left, which gives, 
.
Further, the function is translated 1 unit downward, resulting in .
So, the correct options are,
It has amplitude of .
It is a horizontal shift of the parent function units left.
Times bottom equation by 3 and top by 2 to get the same coefficient of x
6x-6y=60
6x+3y=33
Minus the bottom by the top
-9y=27
y=-3
substitute this in to one of the equations
2x -3 = 11
add 3 to both sides
2x=14
x=7
The function would be f(x)=11,500-.16xPlug in 4 for x
I would just round up to 200 and then subtract twelve or just subtract 200 what ever way u prefer.
To answer this you need to make simple thought experiment. Since the number of sales after time passes cannot go negative (note that rate at which copies are sold can drop over time but total number cannot) that means that you are adding number of sales at first hour and during first hour.
first option cannot be the answer because you are subtracting 100 copies to total number of sold copies which is not logical.
The answer is D) s(x) = 100 + 12(x-1)
after 1 hour (if you replace x with 1 in equation above) you will get 100 copies which matches conditions in the text.
