Question 5: What do we use for n in the compound interest formula when we use the term compound annually? Compound semi-anually? Comound quarterly? Compound monthly? Compound weekly? Compound daily? Evaluate the following compound interest formula for at least 3 compound periods. A = 5000 . (1 4 -12 ) 2.10 Question 6: What did you notice about the amount in the account as you used a larger n for the compound period? A logarithm, the inverse of an exponential function, is simply an exponent. Since exponential functions have the unknown variable x in the power, logarithms allow us to solve for unknown variables found in exponents. The logarithm with base b of x, y - log x, is the power to which b is raised to obtain x, a = by y - log a is equivalent to x = by
