Solution

The function that grows the fastest is A. ๐‘Ž(๐‘ก)=๐‘ก^5/2.

Here's why:

  1. Compare the highest degree of the polynomial functions. The highest degree is the power of the variable that has the highest value. In this case, function A has the highest degree (5/2 or 2.5), which is higher than the degrees in functions B (2) and E (2).

  2. For function C, the natural logarithm function ln(t/100), the growth rate is slower than any polynomial function for large t.

  3. For function D, e(t)=e, this is a constant function and does not grow at all as t increases.

Therefore, function A grows the fastest.
