The exponential function that models this situation is:
------------------------------------------
A decaying exponential function has the following format:
In which:
- y(0) is the initial value.
- r is the decay rate, as a decimal.
In this problem:
- The stock started at $225, thus
. - Declines at a rate of 25% every 2 weeks, thus
The equation is:

64; Line pq is correspondent with line ab and triangle PQR is 4 time as big as triangle ABC.
Simplify in Math, like in English, means to make as simple as possible - as "down to the roots as possible".
In the example = 36 + 10 . To simplify fully would be = 46 since that is as simple as it gets.
In algebra, to simplify fully might involve 14 = 2x, where to simplify fully would be to find x (x = 7)
Start from inside to the out side of the function;
h(5)=10/5=2
g(h)=g(2)=3*2=6
now, get the f inverse of x;
f(x)=y=x+6
x=y-6
replace x with y and y with x
y=x-6
so f^-1= x-6
so f^-1(g)=f^-1(6)=6-6=0
I am not sure only of the last value, but pretty sure of the rest.
