Sp#5:Unit J Concept 6: Partial Fraction Decomposition with repeated factors

This concept is a bit different from concept 5. There will be repeating factors. For repeated factors, count uo the powers and include the factor as many times as the exponent. Don't forget the negatives and make sure to combine like terms correctly.

Sp#4:Unit J Concept 5: Partial Decomposition with Distinct Factors

Make sure you do not forget any negatives. Also, don't forget to combine oike terms correctly. Lastly, also multiply correctly because it may get confusing.

SV#5: Unit J Concept 3-4: Matrices

I apologize in advanced for the video being choppy and echo-y. Also, when the calculator appears, that means that I am going over how to check your answers.

Be sure that when going over this video, you write down next to the matrix what you are doing to obtain row echelon form. Also, do not forget to not misplace negatives. Lastly, don't forget all the elementary row operations.

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



Some key points to remember is that the asymptope will be veritcal on the graph. Also, dont forget to choose key points that are highet than the asymptope. Lastly, don't forget to use the change of base formula when finding and answer on the calculator.

Sp#3: Unit I Concept 1: Graphing Exponential Functions And Identifying x-intercept, y-intercept, asymptopes, domain, and range

For this equation, play close attention to the signs as it will help determine the range as well as fhr asymptope. Also, dont forget that for the asymptope, y=k. Lastly, pay attention to how you solve for the x- and y-intercepts. These are the things you will have to pay close attention to. Good Luck!

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



Remember to pay attention to what needs to be added and what needs to be subtracted in the expanded log. Also, do not forget the "hidden"clues or the clues which are not originally given. Lastly, don't forget the power power law, which is putting the degree in front of the log.

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



This problem will display what a slant asymptope will look like and how to find it. I will also be going through and explaining how to find the vertical asymptope, the holes, the domain, the x and y intercepts, and how to graph it. I will also show you how to properly graph it after finding all the things I have listed.
Keep in mind to remember that this is a slant asymptope, not a horizontal. Also, remember to factor properly and to use the simplified equation for everything except the y-intercept. Lastly, do not forget that the assistance of a graphing calculator will be of much help.

SV#1: Unit F Concept 10: Given Polynomial of 4th or 5th Degree, Finding All The Zeroes

See video and instructions here.

This video will go over how to find all the zeroes, real and imaginary, from a given polynomial of a fourth or fifth degree. I will also go over previous concepts used to find the possible real zeroes as well as how many possible positive and negative zeroes there are going to be. We will also be reviewing the quadratic formula as well as synthetic division.

Be sure to pay attention to how many possible positive and negative zeroes there will be because in some cases there maybe be no positive and only negative or vice-versa. Also make sure to pay attention to the synthetic division because it can get confusing at times and sometime multiply or subtract incorrectly. Lastly, make sure you use the quadratic formula correctly or else your zero will be incorrect.

SP #2: Unit E Concept 7: Graphing Polynomials

This equation will display how to graph a polynomial and how to graph it. In order to graph the polynomial, you need to factor the equation and determine the end behavior to get an idea of which way the graph goes.  Also, finding the y-intercept, minimum and maximum will help to graph a more accurate graph.
Make sure to pay attention to the multiplicity of the zeroes because they will determine whether the graph will go through the x-axis, bounce off the x-axis,  or curve onto the x-axis. Also be sure you have the correct zeroes as well as the correct amount of zeroes.

SP#1: Unit E Concept 1: Identifying x-intercepts, y-intercepts, vertex, axis of quadratics and graphing them.


This problem will display an equation and and will display how to factor it and turn the factored answer into a parent graph. Also, once you have the parent graph equation, you find the vertex, y-intercept, and axis. To find the vertex, you look at the h and k of the parent graph equation. To find the y-intercept, set all the x's of the parent graph equation to zero then solve. To find the axis, look at the h of the equation and that will be your answer. Lastly, to find the x-intercept(s), you solve the factored equation-not the parent graph equation- and you will end up with two answers. Those answers will be your x-intercept(s).

Be sure to pay attention to which equation is which; in this case be sure to tell which is the factored equation and which is the parent graph equation. Also, remember that the parent graph equation is f(x)=a(x-h)^2+k. Lastly, remember that if you square root a positive, the outcome will have a +- result.
