Algebra.Com's Answer #57143 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! 1)Graph f(x)=(x^2 - 4)/(x - 2) using a graphing calculator. Using a standard window with the trace feature, trace the graph to x=2. What happens? \n" ); document.write( " \n" ); document.write( "At x=2 you get an ERROR. \r \n" ); document.write( "\n" ); document.write( "2. Why is there a \"break\" in the line at x=2? \n" ); document.write( "The denominator cannot be zero; Because there is also a factor of \n" ); document.write( "(x-2) in the numerator you get a \"hole\" in the graph. \n" ); document.write( "---------- \n" ); document.write( " Why is the graph a line without a vertical asymptote at x=2? \n" ); document.write( "If you cancel the (x-2) factor that is common to numerator and denominator \n" ); document.write( "you get the function y=x+2 which graphs as a line. \n" ); document.write( "----------- \n" ); document.write( " If x is \"close to\" 2, what is the y value \"close to\"? \n" ); document.write( "y=4 \n" ); document.write( "---------- \n" ); document.write( "Create a function that has either a hole, a break, or an asymptote in the graph. \n" ); document.write( "Asymptote: y=x/(x-2) will have a vertical asymptote at x=2. \n" ); document.write( "Hole: y=[x^2-3x]/[x-3] will have a hole at x=3 \n" ); document.write( "============= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
