SV#5 - Unit J Concept 3-4:Solving three-variable systems

The viewer needs to pay special attention what row they use to get the triangle of zeroes which is usually the row on top. Also they need to make sure that they distribute the negative correctly. Lastly, you must make sure to add and subtract numbers correctly. Below is the video to see how to use the calculator.

SV#4 Unit I Concept 2- Graphing Logarithmic Functions

You need to pay attention to the change of base in order to get the right equation to plug into your calculator. You also need to ensure that you know how to identify the terms in order to get the right vertical asymptote. Remember that for this problem the range is all real numbers and the the domain is from the vertical asymptote or the h-value to positive infinity.

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

Throughout the problem, you need to pay attention to the factors chosen to get the same variable answers as I did. Also, you need to make sure that the answer is written in the power law form where the exponents go in the right place. Be sure to subtract (divide) and add (multiply) accurately.

SV#2: Unit G Concepts 1-7 - Finding all parts and graphing a rational function

This video is about solving a rational function by finding the slant asymptote, the vertical asymptotes, and the holes. Also, you have to find the domain, the x-intercepts, and the y-intercepts. The problem also involves writing the answers in proper notation and as points to be plotted on the graph.

The viewer has to pay special attention to the division part of the problem by adding the missing terms into the equation. Also, the viewer has to pay attention to the corrected hole y-values that I got by plugging in the hole value to the simplified equation. It would help to pay attention to the values that you are meant to use whether it is the numerator or the denominator.

SV#1: Unit F Concept 10 - Finding all real and imaginary zeroes of a polynomial

This problem is about finding the zeroes of a polynomial equation. You find the p's and the q's in order to find the possible zeroes values. You also use the Descartes Rules of Signs to find how many positive and negative real zeroes there are. Then you use synthetic division to factor the polynomial into a quadratic which you would plug in to the quadratic equation and find the zeroes.

One of the things to pay close attention to is the signs used in order to solve the problem, In other words, you need to make sure to distribute the negative accurately. You need to make sure to write the imaginary zeroes involving the "x" in the problem.
