You can put this solution on YOUR website!
f(x)=5(x)-1 find f(a-2)
\n" ); document.write( "I guess the term (a-2) confuses you.
\n" ); document.write( "The trick is you just need to treat it as x and in this case x=a-2
\n" ); document.write( "then go back to the function f(x)=5(x)-1 and just replace x with a-2
\n" ); document.write( "you will have f(a-2)=5(a-2)-1=5a-10-1=5a-11
\n" ); document.write( "The answer: f(a-2)=5a-11
\n" ); document.write( "
\n" );
