In Logarithms and Logarithmic Functions, our instructor begins with restrictions and the written form of logs. Next up are log functions which have the same restrictions as exponential functions. You will also learn how to graph log functions as well as properties such as continuity, domain, range, asymptote of the y-axis, and the x-intercept. Next are the inverse property, how to deal with equations, and inequalities involving logs. Finally, you will end learning how to deal with logarithms on both sides of equations and inequalities. Four examples at the end make sure you can utilize the new concepts in real world problems.
Know the graph of the exponential function and its properties.
If the base is greater than 1, the function is exponential growth. If it is between 0 and 1, it is exponential decay.
Solve exponential equations with the same base by equating the exponents.
Solve exponential inequalities with the same base by applying the same inequality to the exponents.
