If f(x)=[2x2+2x+11x2+x+4]f(x) = \left[\frac{2x^2 + 2x + 11}{x^2 + x + 4}\right] and g(x)=log⁡2(x2+12x)g(x) = \log_2\left(\frac{x^2 + 1}{2x}\right) , where [x][x] denotes the greatest integer function less than or equal to xx , then range of the function h(x)=log⁡g(x)f(x)h(x) = \log_{g(x)} f(x) is (a) (−∞,∞)(-\infty, \infty) (b) (−∞,∞)−{0}(-\infty, \infty) - \{0\} (c) [−1,∞)[-1, \infty) (d) (−∞,1](-\infty, 1]
