Algebra.Com's Answer #654482 by robertb(5830)![]() ![]() You can put this solution on YOUR website! Case I. f(x) is even. \n" ); document.write( "Then f(-x) = f(x). \n" ); document.write( "==> f(-4x+8) = f(4x-8) \n" ); document.write( "==> f(-4(x-2)) = f(4(x-2)) \n" ); document.write( "==> There is horizontal translation 2 units to the right, and then vertical stretching by a factor of 4. There is no reflection across the x-axis.\r \n" ); document.write( "\n" ); document.write( "Case II. f(x) is odd. \n" ); document.write( "Then f(-x) = -f(x). \n" ); document.write( "==> f(-4x+8) = -f(4x-8) \n" ); document.write( "==> f(-4(x-2)) = -f(4(x-2)) \n" ); document.write( "==> There is horizontal translation 2 units to the right, and then vertical stretching by a factor of 4. There IS reflection across the x-axis.\r \n" ); document.write( "\n" ); document.write( "Case III. f(x) neither odd nor even is similar to Case II. \n" ); document.write( " \n" ); document.write( " |
