Just replace all occurrences of the variable (e.g. x, n) with that number and simplify. For example,\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Things get a little different when the function is not in terms of a simple \"x.\" We can define a function g:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Suppose we want to find the value of g(7). We do not plug in x = 7. Rather we plug in 2x + 1 = 7, which is the same as plugging in x = 3.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
