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( "\"graph%28400%2C300%2C-10%2C10%2C-10%2C10%2C%28x%5E2-4%29%2F%28x-2%29%29\"
\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( "=============
