SV #3; Unit I Concept 2; Graphing Logarithmic functins and identifying x-intercepts, and y-intercepts, asymptote, domain, and range

Graphing Logarithmic equations requires a lot more work than graphing a simple y= equation. The trickiest parts would most likely be finding the x-int. and y-int. In order to find the x-intercept we need to equal the entire equation to 0 and solve from there. In order to find the y-intercept we need to replace the x with a 0 and solve from there. When solving for a Logarithmic equation, it is required to cancel out the log by equaling both sides with the same base. From there and on, everything is pretty simple.

SP #3; Unit I Concept 1; Graphing exponential Functions and Identifying x-intercept, y-intercept, Asymptote, Domain, and the Range

Graphing exponential Functions and Identifying x-intercept, y-intercept, Asymptote, Domain, and the Range includes a few tricky steps. the trickiest step is knowing how to find the x-intercept and the y-intercept. when solving for the x-intercept, one must remember to equal the y to 0. when solving a rule to remember is that there cannot be a negative ln When solving for a y-intercept, one must remember to equal the x to 0. Another rule to remember is that the log (base) answer cannot be a negative.

SV # 3; Unit H, Concept 7: Solving logs Using Approximations

The trickiest, and most important parts to remember about these equations are the rules of exponents. When inputting the log into the equations the proper way to set the exponent is to move it to the front of the log. Another important issue is knowing when to add a negative into the equation. when anything is divided by a number, the first number of the denominator must be changed to a negative because it rotates from the bottom of the division problem into a regular, line equation.

SV #2; Unit G Concepts 1-7: How to solve Rational Functions

In Unit G, we find the slant, vertical,and horizontal asymptotes, as well as it's holes. You first determine whether the graph is a horizontal or slant asymptotes, it can not be both. with either asymptote you would then have to find its holes, if it consists of any, x-intercepts, y-intercepts, domain, and a vertical asymptote. There are specific steps to solving for each item, so pay close attention to the short video of how to solve for a Slant Asymptote. Many key points to remember about this unit, it how to solve for each item. A horizontal asymptote has a bigger degree on the bottom (denominator), while a slant asymptote has a bigger degree on top (numerator). A hole is found when something is able to cancel with the factored out equation. A vertical asymptote is found when equaling the denominator with zero. If there is a Hole, we simply remove the "hole" from the equation. these are the main important issues to focus on when solving a polynomial.
