Unformatted text preview: b. Convert x M a= log to an exponential equation. 15. Suppose a function is defined by f(x) = 100 + 20 ln x a. What is the domain of f? b. Calculate f(1) c. Calculate f(3) 4.4 16. Express in terms of sums and differences of logarithms: 3 4 2 3 5 log x z y 17. Express as a single logarithm: 2[ln(x 2 – 9) – ln(x + 3)] + ln(x + y) 4.5 18. Solve: log(x + 5) – log(x – 3) = log 2 19. Solve: e 2t = 10 20. Solve: log 6 x = 1 – log 6 (x – 5) 4.6 21. A population of rabbits starts with an initial population of 100. The number of rabbits after t days is given by P(t) = 100e 0.117t a. What will be the population after a week? b. What will be the population after two weeks?...
