when x is 0, the value of y is undefined.
\n" ); document.write( "this creates a hole in the graph since there is no value of y that satisfies the equation when x is equal to 0.
\n" ); document.write( "if the numerator is negative, then the value of y will decrease as x approaches 0.
\n" ); document.write( "if the numerator is positive, then the value of y will increase as x approaches 0.
\n" ); document.write( "here's two graphs that show you what i mean.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "first graph is y = -100 / x.
\n" ); document.write( "look at the values of x = -10, x = 0, x = 10
\n" ); document.write( "when x = -10, the value on the graph is -100 / -10 which is equal to 10.
\n" ); document.write( "when x = 0, the value on the graph is undefined.
\n" ); document.write( "when x = 10, the value on the graph is -100 / 10 which is equal to -10\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"graph%28600%2C600%2C-10%2C10%2C-500%2C500%2Cy+=+-100%2Fx%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "second graph is y = 100 / x
\n" ); document.write( "look at the value of x = -10, x = 0, x = 10
\n" ); document.write( "when x = -10, the value on the graph is 100 / -10 which is equal to -10.
\n" ); document.write( "when x = 0, the value on the graph is undefined.
\n" ); document.write( "when x = 10, the value on the graph is 100 / 10 which is equal to 10.\r
\n" ); document.write( "\n" ); document.write( "as the value of x gets closer to 0, the value of y gets larger and larger.
\n" ); document.write( "in other words, it is approaching infinity, but never quite gets there.\r
\n" ); document.write( "
