Logarithms. The mathematics of logarithms and exponentials occurs naturally in many branches of science. It is very important in solving problems related to growth and decay. The growth and decay may be that of a plant or a population, a crystalline structure or money in the bank.
Simplify each of the following logarithmic expressions, giving the final answer as a number not involving a logarithm. a) log 24 log 32 2− b) log 96 3log 2 log 43 3 3− − c) 5 5 5 1 2 log 500 log log 10 5 + − d) 2log 54 log 0.25 4log 23 3 3− − e) 8log 2 log 4 3log 96 6 6− −( ) 3 , 1 , 3 , 6 , 6
A logarithm answers the question: “To what exponent do I need to raise a given base to get a certain number?” For instance, if we have 2 3, the logarithmic equivalent would be log 2 (8) = 3. In this case, the logarithm tells us that we need to raise 2 to the power of 3 to get 8. The general form of a logarithm is written as: log b (y) = x
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)
