Is the function given by g(x) = Vx -7 continuous over the interval [7,co )? Why or why not? Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. No, the function is not continuous at x = (Use a comma to separate answers as needed.) B. Yes, the function is continuous over [7,co) because the values over the interval [7,co) are in the domain of g(x) and lim g(x) = g(a) for all x in [7,co). x- a
