SV#4, Unit I Concept 2: Graphing logarithmic functions and identifying x-intercepts, y-intercepts,asymptote, domain, range (minimum of 4 points on graph)
Click HERE to watch the video:)
This video goes over how to graph logarithmic equations. Focussing on the parts that help creat the graph which are x-intercepts, y-intercepts,asymptote, domain, range (minimum of 4 points). To find the asymptote the viewer should remember that the asymptote is x=h, and that in finding the y intercept x is set equal to zero, and when looking for the x intercept y equals zero. A nothing the viewer should pay close attention to is that range always has no restrictions, while domain is based on the asymptote. The most important thing though is that the graph continues on forever on both sides.

SP# 3, Unit I Concept 1: Graphing exponential functions and identifying x-intercept, y-intercept, asymptote,domain,range (4 points on graph)
and is a horizontal line. As seen in finding the x intercept we do not have one because you can't take the log of a negative number. To find the y intercept you basically just substitute x for zero. Lastly the domain in this case will not have restrictions, the range does and it is based on the asymptote.

SV#3: Unit H Concept 7: Finding logs given approximations
Click Here to view the video:)
Something the viewer need to pay closer attention to would be the hints they can come up with themselves. For example log base b of b equals 1 and log base b of 1 equals zero, those go for all problems having to do with finding logs given approximations. Also when the fraction doesn't allow for any of the clues to divide or multiply into it then you would need to expand it. And make sure to use your properties of logs correctly.

SV#2 Unit G, Concepts 1-7: finding vertical, horizontal, and slant asymptotes of rational functions and holes, domain, x and y intercepts. Graph.
Click Here to watch video :)
This video is about finding vertical, horizontal, and slant asymptotes. Not only that but also finding the holes, y and x intercept, and domain with interval notation. All those specific parts contributing to the specific parts that are included in the graph.
In order to understand the viewer needs to pay special attention to what equation must be used if not you may get completely different answers. Another thing to pay special attention to would be when graphing the hole it's important to leave it as an open circle. One last thing to keep in mind would be that you may never have a horizontal and a slant asymptote, it's either one or the other.
