\n" ); document.write( ": can somebody help me solve this problem: if $\"f%28x%29=3x%5E2-2\"$ then find f(x+h)?
\n" ); document.write( "this is what i did...i plug in the f(x+h) in the f(x) function,
\n" ); document.write( "so $\"3%28x%2Bh%29%5E2-2\"$ , i got 3x+3h-2,but i'm not sure if this is the right answer,because 3x is raised to the 2nd power in the f(x)...please tell me if i'm wrong \n" ); document.write( "
