\n" ); document.write( "\n" ); document.write( "They want you compare the plot y = (2x)^2 with the plot of the parent function y= x^2.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "        There are  TWO  EQUIVALENT  descriptions of this transformation.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "One description says that the plot is  COMPRESSED horizontally  with the coefficient of  2.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The other description says that the plot is  STRETCHED  vertically with coefficient of  4.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "For given problem,  both these descriptions are  EQUIVALENT,  as I just said above.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "They are equivalent, because the function has two equivalent presentations\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "             y = (2x)^2 = 4*x^2.\r
