Given: f(x)=8-5x
\n" ); document.write( "A. Find f(-2)\r
\n" ); document.write( "\n" ); document.write( "f(x)=8-5x
\n" ); document.write( "
\r\n" );
document.write( "Everywhere there is an x, substitute (-2) instead:\r\n" );
document.write( "\r\n" );
document.write( "f(-2) = 8-5(-2)\r\n" );
document.write( "\r\n" );
document.write( "Simplify\r\n" );
document.write( "\r\n" );
document.write( "f(-2) = 8+10\r\n" );
document.write( "\r\n" );
document.write( "f(-2) = 18\r\n" );

document.write( "f(x)=8-5x\r\n" );
document.write( "\r\n" );
