f(x) = |x|
\n" ); document.write( "1. Stretch vertically by a factor of 4: Multiply the current f(x) (i.e. y) by 4
\n" ); document.write( "f(x) = 4*|x|
\n" ); document.write( "2. Reflect about the x-axis: Replace the current f(x) (i.e. y) with its opposite/negative
\n" ); document.write( "f(x) = -(4*|x|) = -4*|x|
\n" ); document.write( " \n" ); document.write( "
