Unformatted text preview: and 6 # x 4 / x So the solutions are 6 and 4. Mistakes: 1. We dont divide by log. 2. Must eliminate 4. 2. A student has to solve a system of equations ) 1 log( 2 3 # # # x y x y . He decides to graph both equations. The student then copies the following diagram to his worksheet. a. What is wrong with his diagram? Graph of log( 1) x # is graphed incorrectly 1. It goes through the point (2,0) 2. The leftside of the graph doesnt end b. Will the two graphs have an intersection? Yes c. Will the solution (if there is one) be less than or greater than 1? Explain how you know that, without actually drawing more of the diagram. Must be greater than 1 since the domain of log( 1) x # is ! " 1, ,...
