You can put this solution on YOUR website!
If f(x)= 4x -3, find the following:\r
\n" ); document.write( "\n" ); document.write( "f(-1)\r
\n" ); document.write( "\n" ); document.write( "What f(-1) tells you to do is to start with f(x) = 4x - 3, then replace every x you see
\n" ); document.write( "in it by (-1), and finally compute what the right side equals.
\n" ); document.write( ".
\n" ); document.write( "Let's change the problem a little and find f(-4). Go to the expression f(x) = 4x - 3 and
\n" ); document.write( "replace all the x's by -4. When you do the expression becomes:
\n" ); document.write( ".
\n" ); document.write( "f(-4) = 4(-4) - 3
\n" ); document.write( ".
\n" ); document.write( "When you multiply 4 times -4 you get -16. Substitute -16 for 4(-4) and the expression
\n" ); document.write( "becomes
\n" ); document.write( ".
\n" ); document.write( "f(-4) = -16 -3 and the two terms on the right combine so that the expression becomes:
\n" ); document.write( ".
\n" ); document.write( "f(-4) = -19
\n" ); document.write( ".
\n" ); document.write( "You can do the work to find f(-1). Follow the same process as the example.
\n" ); document.write( ".
\n" ); document.write( "I hope this helps you to understand what the problem really means. \n" ); document.write( "
\n" );
