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




     Viewers need to pay special attention to the x-intercept, in that to get rid of the log and its base, you exponentiate so you cancel the log and remember that the other number on the other side is now the exponent and the number that it was exponentiated by is their main number. The viewers also need to pay special attention to the y-intercept, in that it does not have a common log so you have to divide by natural log or logarithmic to get rid of the log in the equation. When ever dealing with graphing a logarithmic function, your range will always be (negative infinity, infinity) and your domain will be the number you got as your "x" in the asymptote, and that will be your point for the domain; (x, infinity). Also take note that a logarithmic function graph goes to the right. Thank you for watching and have a nice day!

SP #3: Unit I Concept: 1 Graphing Exponential Functions


     The viewers need to pay special attention to the x-intercept. There is no x-intercept because "-5/3" is a negative number and you cannot have a negative number when dealing with logs; so the equation will not work. The viewers also need to pay special attention to the exponents because when you have a fraction as your main number and you have a negative exponent, the fraction will turn into a whole number; but this does not apply for this situation, so you do not have to worry. Also, they need pay special attention to the domain and the range; there is no x-intercept so your domain does not have a limit to it so your domain will be (negative infinity, infinity); since your asymptote is 5 and your equation is positive, then you know the limit notation will be (5, infinity).

SV #3: Unit H Concept 7: Finding Logs with Given Approximations



     The viewers need to pay special attention to how to break down a number using their clues. Try to use the numbers in your clues so you can plug in those numbers at the end when your bring them down. Also, remember if the log has a power in it, remember to put it in the beginning of the log and bring it down when you get your final answer. The viewers also need to make sure they know how to convert the powers into radicals or the opposite of that. The positive numbers always go on top as the numerator and the negatives go on the bottom as the denominators.

     For those wondering why I chose K-R-I-S as my clue words, it was because I'm a big fan of EXO and I thought about Kris since we need to use 4 logs in the equations and also because I love him. My Kris Oppa so happened to have four letters in his name, so it was enjoyable to involve Kris Oppa into my equation. Thank you for watching!

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



     This problem is about everything with rational functions! You will learn about finding horizontal asymptote, slant asymptote, vertical asymptote, hole(s), domain, x-intercept(s), y-intercept(s), and how to graph them. You will also learn the difference between each asymptote and their rules.

     The viewers need to pay special attention to limit notation for the vertical asymptote since it involves using you graph. If you put in your equation wrong in your calculator, then the graph will be wrong and your notations will be wrong, so you need to pay attention to also where the graph is and where it is going. The viewers also need to pay special attention to when the equation has a hole, to you the factored equation instead of the original equation because the equation will not work out, so you the factored equation instead!
