  2. 11. Draw the graph of each of the following logarithmic functions, and analyze each of them completely. (1) f(x) = logx (2) f(x) = log x (3) f(x) = log(x 3) (4) f(x) = 2log 3 (3 x) (5) f(x) = ln(x+1) (6) f(x) = 2ln 1 2 (x+3) (7) f(x) = ln(2x+4) (8) f(x) = 2ln( 3x+6)

  3. logarithm of a number, all you have to do is count its digits. For example the number 83,176,000 has eight digits, and therefore its log must be between 7 and 8. And since it’s a large eight-digit number, the log is closer to 8 than 7. (In fact, the log of this number is approximately 7.92.) Here’s the graph of positive base-10 logarithms ...
