In this video lesson we explore how to quickly graph exponential and logarithmic functions, as well as their basic properties in order to simplify and solve exponential and logarithmic equations and expressions.
We start by looking at the four basic exponential graphs in order to investigate how to find asymptotes, direction, and whether the function will rise or fall. We then put these skills to good use by walking through several examples.
We then review how to graph logarithmic functions by, once again, exploring the four basic log graphs and investigating specific techniques on how to find asymptotes, direction, etc. Once again, we then use our skills by walking through several examples. Similar to the “pre-calculus review video #1” we will also discuss the notion of domain and range and symmetry for these functions.
After graphing exponential and logarithmic functions, we then discuss their basic properties and how we use them to simplify expression and solve equations. Together we will review many examples, some of which have come directly from released exams, in order to better sharpen our abilities.
These skills are paramount for any calculus student, because all calculus students will be expected to simplify their answers using the techniques of exponential and logarithmic functions.
