SV#4: Unit I Concept 2: Solving and Graphing Log Equations

The viewer needs to pay attention to the graphing the asymptote, as X creates a vertical line. Also, the viewer must acknowledge that you have to exponentiate the log in order to solve for the x-intercept. The viewer must know the different between how to find h, and that it is opposite of what it is in the equation. Lastly, the viewer needs to understand how to plug in points into the calculator and how to use the log base formula.

SP #3 Unit I Concept 1:Graphing Exponential Functions

The viewer needs to pay attention to solving the x-intercept. If you get a negative log, you have to make sure to know that you cannot take the log of something. Therefore, the x intercept is undefined and there is no x-intercept. Also you must acknowledge that the range changes all the time because it depends on the asymptote. If it the graph is below the asymptote, the  graph will go up until the asymptote. If it is above, it will start at the asymptote to infinity.

SV #3: Unit H Concept 7: Finding logs given approximations

This problem is about finding logs, given approximations. To clarify, you will be given variables that are equal to logs, that add or subtract to your solution. You will expand your clue using the properties of logs. The quotient law, product law, and power law are present in this type of equation. You will also be substituting your values (letters) given.

The viewer needs to pay attention to that sometimes, the clues given does not match up to the log you are finding. To fix this, the viewer needs to multiply the numerator and denominator continuously until both the bottom and top have factors of the given clues. The viewer also has to make sure not to confuse the quotient law with the product law. The quotient law is when you divide, your logs can subtract. The product law is that when you multiply logs, that means you can add them too.

SV #2: Unit G Concept 1-7: Graphing Rational Functions

     This student video is about finding slant, horizontal, and vertical asymptotes. You will also be finding holes and the domain. After finding these, you can graph the function. A hole is a place where the graph cannot  touch. We will also be finding limit notation and using our calculator to help us.
     When doing this problem, you must take note that when we find our holes, we need to make sure it gets plugged into the simplified equation. We also have to pay attention to when we plug in the equation to the calculator, we must use parantheses. Another crucial thing that the view needs to pay attention to is the view must not confuse how to find x intercept and y intercept. for X intercept, you set y to 0. For Y intercept, you set X to 0.
