Range of the function f (x)= sqrt(x ^(2) + x +1) is equal to

Range of the function f (x)= sqrt(x ^(2) + x +1) is equal to

The value of lim_(x to oo) (sqrt(x^(2) + x + 1) - sqrt(x^(2) - x + 1)) equals

Simplify : (x + sqrt(x^(2) - 1))/(x - sqrt(x^(2) -1)) + (x - sqrt(x^(2) -1))/(x + sqrt(x^(2) -1)) If the result of the simplification is equal to 14, then find the value of x

int (4x + 2) sqrt(x^(2) + x + 1) dx .

int sqrt(x^(2)+x+1)dx
