Algebra.Com's Answer #50658 by bucky(2189)![]() ![]() ![]() You can put this solution on YOUR website! This problem is just a case of understanding what the notation means. You are given \n" ); document.write( "that \n" ); document.write( ". \n" ); document.write( "f(x) = 4x - 3 \n" ); document.write( ". \n" ); document.write( "Then you are asked to find f(-1). Notice that in f(x) the x has been replaced by -1 for x. \n" ); document.write( "So what you are being told to do is replace x by -1 in the equation f(x) = 4x -3. \n" ); document.write( "When \n" ); document.write( "you make that replacement you get: \n" ); document.write( ". \n" ); document.write( "f(-1) = 4*(-1) - 3 = -4 - 3 = -7 \n" ); document.write( ". \n" ); document.write( "So you can say f(-1) = -7 for this particular problem. \n" ); document.write( ". \n" ); document.write( "That's all there is to it. Hope that this helps your understanding of the problem \n" ); document.write( "and the notation it involves. \n" ); document.write( " |
