SV #5: Unit J Concept 3 - Gaussian Elimination

SV #4: Unit I Concept 2 - Graphing Logarithmic Equations
Some important things that need to be noted whilst completing problems of this particular field of study, are: remembering how these types of problems share the same structure, remembering how you find the asymptotes for logarithmic equations, and remembering the domain/range of logarithmic equations. First of all, the parent type function for these problems is log base b of (x minus h) plus k. Second of all, the asymptotes for logarithmic equations will always be x = h, and you can remember this specific rule with the phrase "The Log's Xylophone was Happy and Rich", where you derive x = h from "Xylophone was Happy". Lastly, the domain of logarithmic equations will always be restricted (unless there's no h value), and their ranges will never be restricted. This can also be remembered by the previously noted phrase, and is extracted from "Rich", in which the r proclaims that the range is to never be restricted. The end.

SV #3: Unit H Concept 7 - Expanding Logarithms
Some important things you must pay attention to are how you synthesize logarithms from factors of big numbers, and remembering to substitute in the variables. Also, you must remember to utilize the properties of logs in order to formulate more logarithms that you may be required to utilize in order to get to the desired endpoint. Another somewhat important thing to remember to do is to turn the denominator log into subtraction. Lastly, if none of the given clues can fit in, you may be able to multiply the endpoint in order to factor the number. Either that, or you're wrong. Anyways, the end.

SV #2: Unit G Concepts 1-7 - Finding All Parts and Graphing A Rational Function
Some special things that you need to remember are what to do to find stuff, how to graph, and how to put all of this into your calculator to make it easier and or check. Anyways, you always have either a horizontal asymptote (ratio for same degree on top and bottom, y = 0 for degree being bigger on bottom), a slant asymptote (when the top degree is bigger by 1, y equals the numerator divided by the denominator, leaving out the remainder), or none (when the top degree is bigger by more than 1). To graph, all you do is just kind-of make lines parallel to the asymptotes, and that will reach infinity on some value. To put all of this into your calculator, you might have to just do it. That is all.

SV #1: Unit F Concept 10 - Finding All Real and Imaginary Zeroes of A Polynomial
Some important things that one must pay attention about in order to master this concept include remembering to use the rational roots theorem, and the Descartes Rule of Signs, and remembering to put zeroes in to fill voids when an x is missing in the polynomial. The most important thing, however, is to remember that you may more easily complete this process by utilizing a graphing calculator in order to identify zero heroes. But, as scholars, is it not more honorable to walk the path filled with thorns in order to ensure our complete mastery of this concept? Either way, yeah; it is easier to use the graphing calculator.
