Calculate the area in between these two functions: - - f(x) = x 2x + 6 and g(x) = 1x + 4x 6 = from x = 3 to x = 6. (HINT: f(x) is always greater than g(x) over this interval.) Drawing a sketch of the graphs may help but it is not required. 4 321 -1- -2- - 3 - 4 TL 1 2 3 4 5 $18,000 is deposited into a bank account that earns interest at a rate of 3.6% per year, compounded continuously.
