Question 116512: My question is not just a function it is one that is (f of g)(x)
where f(x)= 2/x-8 and g(x)= 7/4x. I thought you put g(x) in for f(x) but how does that work with this problem? This is from a past test of mine that might be on my final. Thank you so much for your help!

Question 116885: The formula for calculating the amount of money returned for an initial deposit into a bank account or CD (certificate of deposit) is given by A=P(1+r/n)^rt
A is the amount of the return.
P is the principal amount initially deposited.
r is the annual interest rate (expressed as a decimal).
n is the number of compound periods in one year.
t is the number of years.
Carry all calculations to six decimals on each intermediate step, then round the final answer to the nearest cent.
Suppose you deposit $4,000 for 8 years at a rate of 7%.
Calculate the return (A) if the bank compounds monthly (n = 12). Round your answer to the hundredth's place.
