Section 1. 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.
These problems are designed to build a strong foundation by encouraging students to calculate common logarithms such as log 10 10, log 10 1, log 10 100 and more. These fundamental exercises are critical for understanding how logarithms work in various applications and prepare students for more challenging logarithmic equations.
Logarithms are the mathematical function that is used to represent the number (y) to which a base integer (a) is raised in order to get the number x: x = ay; where y = loga(x). Most of you are familiar with the standard base-10 logarithm: y = log10(x); where x = 10y.
Given that log 2 = x, log 3 = y and log 7 = z, express the following expressions in terms of x, y, and z. (1) log 12 (2) log 200. 14. (3) log (4) log 0:3. 3. (5) log 1:5 (6) log 10:5 6000. (7) log 15 (8) log. 7.
Section 6.3 Logarithms and Logarithmic Functions 313 Graphing Logarithmic Functions You can use the inverse relationship between exponential and logarithmic functions to graph logarithmic functions. Graphing a Logarithmic Function Graph f (x) = log 3 x. SOLUTION Step 1 Find the inverse of f. From the defi nition of logarithm, the inverse of f ...
