SV #4: Unit I Concept 2: Graphing Logarithmic Functions

Click Here

This video goes over logarithmic functions and also includes the parts that help find the graph to it. There are many key factors that you must pay attention to because this time around there's a log involved. Given this information, you know that for the x-intercept, we have to exponentiate in order to get rid of the log. Also, for the y-intercept, you must remember to change the base in order to figure our the ordered pairs. Also, in order to graph the equation, you need key points of significance. However, in order to get thoe points, you first need to plug it into your calculator the way I described in the video, so please make sure to do this before continuing. Lastly, as a clarification, the graphing calculator will not entirely graph the equation correctly, so the part left of -5, which is the asymptote, will be blank because of that same reason. Don't worry though, you do not need to graph that section. Other than that, thank you for watching :D
