SV#4: Unit I Concept 2: Graphing logarithmic functions and identifying x-intercepts, y-intercepts, asymptote, domain, range



Pay close attention to the use of logs and the concepts we already went over in the previous unit. This is because solving and graphing logarithmic equations involves a lot of these necessary skills! Make sure you did all the work and understand it before moving on. Also remember the parent functions and the phrase that helps us remember what the range is and where we can find the asymptote.

Thanks for watching! Have a good day! 

SP#3: Unit I Concept 1: Graphing exponential functions and identifying x-intercept, y-intercept, asymptotes, domain, and range

Pay special attention the the use of logs throughout the template because these skills you need to master to draw these types of graphs! Make sure you understand the reasons why there are no x-intercepts. Please make sure you know how to plug the equation into your graphing calculator and how to find the key points because the minimum is 4. Memorize the parent functions and good luck!

SV #3 Unit H Concept 7 Finding logs given approximations



This student video is about finding logs given approximations like finding treasure given clues. Clues all have the same base and different variables. You find those variables from dividing the log you have to find into the factors from the clues. These factors will tell you which variables are used and how you will construct them. You use prior knowledge from concept 5. 

Make sure to pay attention to how I am finding the factors like how you find prime numbers (which all of my factors/clues are!). You may also want to pay attention to all the properties that go into expanding logs. Make sure all your calculations are correct, your division does not have to be the same as mine because you will get the same answer as me as long as they are the whole numbers given in the clues. 

Thanks for watching! I finally fixed the quality of everything so my videos will be a lot nicer!! woot!

SV #2 Unit G Concept 1-7 Graphing Asymptotes



This problem is about Graphing Asymptotes covering concepts 1-7. The video explains how to find the asymptotes and how to solve for them. It also explains how to find holes, the domain, and axis intercepts. Then, it shows how to graph everything from the asymptotes to the axis-intercepts. 

Make sure to pay special attention to how all of the steps are done such as the long division for the slant asymptote, factoring for the vertical asymptote, and canceling for the holes. The rest should be review. You may also want to pay attention to how I got the graph and check your work and your graphing calculator to see if you and I got the same answer. 

Thanks for watching! I really need to find a better program to record my screen resolution (at least you can hear what I'm talking about) so sorry for that. . .
