Final answer:
Without the specific function provided, we cannot determine the exact range for function m. The range of a function is the set of possible values it can take, which can either include all real numbers, be bounded, or be unbounded. The range is given in interval notation, and the function's formula must be known to establish its range.
Step-by-step explanation:
To determine the range of a function, we need to look at the possible values the function can take. However, the question does not provide the actual function m. Without knowing the specific function, we cannot accurately provide its range. The potential options for the range in the question indicate that the function's range either includes all real numbers, is bounded below by 1, or is unbounded both above and below.
If a function's range is all real numbers, this means that there is no number that the function cannot reach. For example, the function f(x) = x has a range of (-infinity, infinity), which corresponds to option C, representing all real numbers. However, if a function never takes on values below a certain number, its range would be bounded below by that number. An example of this would be f(x) = x^2 + 1, which never goes below 1, so its range is [1, infinity) as in option B and D.
Without the specific function, we can only give a generalized overview on how to find a function's range and what the different options in this multiple-choice question would mean in context.
