Algebra.Com's Answer #29064 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! To find the original f(x) we need to multiply \n" ); document.write( "(x^2 + 3x - 5) by (x - 3) and then adding 2...we get \n" ); document.write( "f(x) = x^3 - 14x + 15 + 2 \n" ); document.write( "f(x) = x^3 - 14x + 17 \n" ); document.write( "so that \n" ); document.write( "f(3) = 3^3 - 14(3) + 17 \n" ); document.write( "f(3) = 27 - 42 + 17 \n" ); document.write( "f(3) = 2 \n" ); document.write( "Close, but I get positive 2, not -2. \n" ); document.write( " |
