Option C: is the function that represent exponential decay.
Explanation:
The exponential decay can be represented by
where
and
Option A:
From the function, we can see that and
Thus, and
Thus, the function does not represent exponential decay.
Hence, Option A is not the correct answer.
Option B:
From the function, we can see that and
Thus, and
Thus, the function does not represent exponential decay.
Hence, Option B is not the correct answer.
Option C:
From the function, we can see that and
Thus, and
Thus, the function represent exponential decay.
Hence, Option C is the correct answer.
Option D:
From the function, we can see that and
Thus, and
Thus, the function does not represent exponential decay.
Hence, Option D is not the correct answer.
Answer:
Third option.
Step-by-step explanation:
In the picture attached, the question is shown. There we can see that as x gets bigger (x → ∞), f(x) gets smaller (f(x) → -∞ ). On the other hand, as x gets smaller (x → -∞), f(x) gets bigger (f(x) → ∞ ).
