The number of mosquitoes active near a pond is given by the function f(x)=32x−2 , where x is the number of minutes after dusk

Is the interval (0, 5) a reasonable solution to describe when there are fewer than 6561 mosquitoes active?


Yes. The interval (0, 5) is a reasonable solution because the endpoints are positive values for time.

No. The interval (0, 5) is not a reasonable solution because the function is negative in that region.

No. The interval (0, 5) is not a reasonable solution because the left endpoint results in a fraction value for the function and there cannot be a fraction of a mosquito.

Yes. The interval (0, 5) is a reasonable solution because the function is positive in that region.
