\n" ); document.write( "\"f%28x%29+=+%28x%2B1%29%5E%283%2F4%29\"\r
\n" ); document.write( "\n" ); document.write( "\"f%28x%29+=+root%284%2C%28x%2B1%29%5E3%29\" ...as you can see, the radicand is \"%28x%2B1%29%5E3\" and if radicand is greater or equal to zero solution will be a real number\r
\n" ); document.write( "\n" ); document.write( "so, it will be equal to zero if \"%28x%2B1%29%5E3%29\" =>\"x=-1\"-first solution that is real number, and all solutions that are real number will be if \"x%3E=-1\"\r
\n" ); document.write( "\n" ); document.write( "answer: the values of \"x%3E=-1\" for which f(x) is a real number\r
