Hello again! I'm in need of some help with these two parts.

Find the value(s) ofkfor which the equation x + 1 + (1/x) - k = 0, x not equal to 0, has no real solutions.

A second function is defined as g(x) = b/(f(x)), b greater than 0, where f(x) = (x^2 + x + 1)/(x), x not equal to 0. Determine the range of g(x), leaving the answer in terms of b, and clearly explain your reasoning.
