    So as to have the function be increasing, 2016-m2 must be positive. Therefore, 2016 must be greater than m2. Since 2016 is a positive number, m has to range from \(-\sqrt{2016}\) to \(\sqrt{2016}\). In other words, m has to be between -44.899 and 44.899. Since m is a whole number, the minimal value of m is -44 and the maximum is 44. To calculate the number of values, we use this formula:
    \(N=\frac{44-(-44)}{1}+1=89\)

    To conclude, there are 89 values of m such that the function is increasing.
