Quizplus · Accepted Answer

Since the base of the exponential function is a positive number, the only way for the function to equal a negative number is if the exponent is odd. However, in this case, the exponent is not an integer. Therefore, the function can never equal a negative number. The only choice that is not a negative number is C, which is approximately 9.
