Algebra.Com's Answer #62014 by rapaljer(4671)![]() ![]() You can put this solution on YOUR website! This is true ONLY for non-negative values of x. Therefore, it is not an identity, is it? An identity is true for ALL values of the variable. I suppose you could say that if you are considering ONLY non-negative values of x, then it is an identity. I guess it depends upon what you mean by \"identity.\"\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "R^2 at SCC\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
