For this case we have the following equations:
We must find
By definition of composition of functions we have to:
So:
We must find the domain of f (g (x)). The domain will be given by the values for which the function is defined, that is, when the denominator is nonzero.
So, the roots are:
The domain is given by all real numbers except 0 and 3.
Answer:
x other than 0 and 3
Compound Interest Formula:
P = initial investment of 20,000
r = interest rate (What we need to find)
n=number of compounding periods per year (Semiannually means twice per year)
A= Amount after t-years
Okay, let's plug it all in.
41,951 = 20000 (1 + r/2)^2(30)
41,951/20000 = (1 + r/2)^60
(41,951/20000 )^1/60 = 1 + r/2
(41,951/20000 )^1/60 - 1 = r/2
2( (41,951/20000 )^1/60 - 1 ) = r
0.02484539... = r
0.02484 * 100 = 2.48% rounded to the nearest hundredth of a percent
I hope I've helped! :)
