Question

Select all the correct statements. Which of the following are examples of exponential growth functions?

1. y = 5(1.01)t
2 . y = 0.25e-1.1t
3. y = 11(1 - 0.0001)4t
4. y = 3e0.00001t
4. y = 11(0.95)t
5. y = 1,000(0.23)-1.2t

Answer 1

Answer: The answer is (1), (3) and (5).

Step-by-step explanation: We are given six functions, out of which we are to select the correct ones which are the examples of exponential growth functions.

We know that an exponential growth function is of the form

`y=a^x,`

where a > 1.

From the given options, we have the following exponential growth functions:

`(1)~y=5^(1.01t),\\\\(3)~y=11^((1-0.0001)4t),\\\\(5)~y=11^(0.95t).`

Thus, (1), (3) and (5) are the correct options.
