Student video 4 Unit I concept 2: Graphing logarithmic functions and identifying x-intercepts, y-intercepts, asymptote, domain, range



Things that viewers need to pay close attention too is expontiating the log and using the powers accordingly such as 2^3=8. Viewers also need to pay close attention when plugging in the equation that they use the change of base formula. Also pay close attention to the domain and range and not switch the two up according to the last concept.

SP #3: Unit I Concept 1: Graphing exponential functions and identifying x-intercept, y-intercept, asymptotes, domain, range (4 points on graph minimum


To solve you must find the variable in the equation which are a, b ,h, and k. For the key points our third point is always H. The asymptote is y=k  For our x intercept we set y=0 and solve from there, since our product results in a negative we cant natural log so therefore we have no x intercept. To obtain our y intercept we set all our x values to 0 and solve. Our domain is always all real numbers. Since our graph is above our range is our asymptote which is 2 to infinity. (2,infinity)  

The problem is about finding  everything stated in this chart. Finding our separate variables, keypoints asymptotes, x intercept, y intercept, domain, range, and our graph.

The viewer should play close attention to the different types of variables and how they act.
The A is used to determine if the graph is above or below based on the signs. The H is used to determine the third point on the key points. Our K is used to represent our asymptote.

Student Video #3: Unit H Concept 7: Finding logs given approximations



Things that need to pay close attention too are the numbers being factored and if they relate to the clue or not. Another thing to pay close attention too is to not factor the whole thing to its roots, only to the clues given. The thing to pay close attention is to make sure the power is brought down in front of the log.

Student Video #2:Unit G Concept 1-7



This problem is about determining whether if its a horizontal asymptote or a slant asymptote.  Then we find the vertical asymptotes and determine if there are any holes to be found. We then search for the domain and its interval notation. We also find the X intercept and the Y intercept.

The viewer needs to pay close attention to the degree to determine if its horizontal or a slant asymptote. Another important thing to pay close attention too is the vertical asymptote and look for holes. What ever is crossed out becomes a hole and the remainder is our simplified equation and our vertical asymptote.
