SV #4: Unit I Concept 2 - Logarthmic equations

It is important to be careful that your h, when negative will look positive in your equation. Say your h is -3... it will look like (x+3). Be sure to remember that your equation originally looks like this (x-h). Another thing to be extremely careful is that when plugging in your equation, you cannot just plug it in how it looks. You must use your knowledge from UNIT H of Change of Base formula. Plug in ln(x-h)/ln b +k. Also, keep in mind, when you graph the equation (in your calculator), the graph will seem as if it does not continue on forever (in concerns for range). However, your function does indeed go on forever, the calculator just does not show it. Make sure when you draw your own, draw arrows indicating that it continues on.
