Let f(x)= 2x-3 and g(x)= x^2+2x find the following expressions\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " f(1) substitute 1 in for x in f(x) and simplify.
\n" ); document.write( "f(1)=2(1)-3
\n" ); document.write( "f(1)=2-3
\n" ); document.write( "\"highlight%28f%281%29=-1%29\"
\n" ); document.write( ":
\n" ); document.write( " g(-2) substitute -2 in for x in g(x) and simplify.
\n" ); document.write( "\"g%28-2%29=%28-2%29%5E2%2B2%28-2%29\"
\n" ); document.write( "g(-2)=4-4
\n" ); document.write( "\"highlight%28g%28-2%29=0%29\"
\n" ); document.write( ":
\n" ); document.write( " f(3a) substitute 3a in for x in f(x) and simplify.
\n" ); document.write( "f(3a)=2(3a)-3
\n" ); document.write( "\"highlight%28f%283a%29=6a-3%29\"
\n" ); document.write( ":
\n" ); document.write( " f(3)+g(4) substitute 3 in for x in f(x) and 4 in for x in g(x) and add them together.
\n" ); document.write( "\"f%283%29%2Bg%284%29=%282%283%29-3%29%2B%28%284%29%5E2%2B2%284%29%29\"
