Answer: Second option.
Step-by-step explanation:
Given the function f(x), which is:
And given the function g(x), which is:
You need to substiute the function into the function in order to find 
.
Therefore, through this procedure, you get this answer:
You can observe that this matches with the second option.
Part A
Chorus:
Expontential growth = b*a^x
b = 15
a = 1.12 (a= r+1), r = 12%
Which gives a function of f(x) = 15*1.12^x
Band
Linear growth = ax+b
a = 2
b = 30
Which gives a function of g(x)=2x+30
Part B:
f(9) = 15*1.12^9 = 41.59
g(9) = 2*9+30 = 48
Part C:
This is probably problem solving, where you're allowed to use calculators and other softwares.
Therefore you can use different softwares, and make f(x) = g(x).

Answer:
w = -8
Step-by-step explanation:
Distribute: -6 = 2w + 10
Remove the 10: -6 -10 = 2w +10 -10 ---> -16 = 2w
Isolate the variable: -16/2 = 2w/2
Answer: -8 = w
X-(x+4)=-4
X-x-4=-4
-4=-4
All real numbers
This is an interesting problem. You have to get the absolute value by itself. So divide by -4.
An absolute value can NEVER be a negative number.
