Which of the following are exponential functions?

Hence, the correct option are .

Step-by-step explanation:

Given: Exponential functions

As we know that:

Exponential function has the form of .

From the given option:

:   and is in power;  

:    and is in power.

Here, But options  do not represent the exponential functions, as

:  , so it is not satisfying the condition of exponential function.

: is not in the power.

Hence, the correct option are .

Exponential function is the function of the form where

Options A and D are options that represent exponential functions, because:

A: and x is in power;

D: and x is in power.

Options B and C do not represent exponential functions, because:

B: and, therefore, for example, is undefined.

C: x is not in power.

correct choices are A and D
