Make sure to pay special attention to your matrices and that all the numbers you write are correct because even if you forget something like a negative sign, then your entire answer will be wrong. You should also be careful about your elementary row operations to make sure your able to get Row-Echelon form and check your graphing calculator to check if your answer is indeed correct.

SV#4: Unit I Concept 2- Graphing Logarithmic Functions
To view my video, please click here.
Make sure to pay special attention to the asymptotes and x/y intercepts. Since this is a logarithmic function, the asymptote will depend on h, not k like in exponential functions. So if you forget to take the opposite of h, then your graph will be wrong. For the x/y intercepts, you need to know how to exponentiate and solve logarithmic equations since they can get a little tricky or undefined.

SV#3: Unit H Concept 7 - Finding Logs Given Approximations
To view my video, please click here.
This video will over how to find logs when given clues on how to find it. There are four clues that are given to you and two hidden clues that you can find using your knowledge of the proerties of logs. Using the clues and the power, quotient, anx product property, you will then be able to substitute the values/variables in and simplify to find what the log will equal.
Make sure to pay close attention to breaking down the numbers because some might already be a clue, but could still be broken down further. Also, ensure that you have the right signs when substituting in the clues: if it's in the numerator, then it will be positive because it multiplying; if it's in the denominator, then it will be negative because it is dividing.

SV#2: Unit G Concepts 1-7 - Finding all parts and graphing a rational function
To view my video, please click on the link here.
This video will go over rational functions and how to graph them. It will go also go over your knowledge on horizantal/slant/vertical asymptotes, holes, domain, and the x/y intercepts. Make sure you remember to put everything in its proper notation as well.
You need to make sure to pay close attention factoring and long division. This will ensure that your vertical asymptotes and holes are correct while also helping establish a boundary for your graph. Also, make sure that you have at least 3 points on each side of your asymptotes before making the graph.

SV#1: Unit F Concept 10 - Finding all real and imaginary zeroes of a polynomial
To view my video, please click on the link here.
This video will go over how you can find all the real and complex zeroes of a polynomial. It will draw upon your knowledge from Descarte's Rule of Signs, your p's/q's, synthetic division, and factoring.
You need to pay close attention to when you are factoring, so you can get all the right signs and numbers, when you are using synthetic division, and well basically everything. This is the type of problem that if you get 1 tiny detail wrong, the rest of your answers will be wrong as well.
