Question
Which of the following functions grows the fastest?A.๐(๐ก)=๐ก52a(t)=t 25โ B.๐(๐ก)=๐ก2โ5๐กc(t)= t 2 โ5tโ C.๐(๐ก)=lnโก(๐ก100)i(t)=ln(t 100 )D.๐(๐ก)=๐e(t)=eE.๐(๐ก)=3๐ก2โ๐กg(t)=3t 2 โt
Solution
The function that grows the fastest is A. ๐(๐ก)=๐ก^5/2.
Here's why:
-
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).
-
For function C, the natural logarithm function ln(t/100), the growth rate is slower than any polynomial function for large t.
-
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.
