Question

Which of the following is a parent function

Answer 1

Answer:

the last one

Step-by-step explanation:

Answer 2

Answer:  

The correct option is D

Step-by-step explanation:

$\text{A. f(x) = }x^4 +3$

The parent function can be x but in this case it is translated so the translated function cannot be a parent function.

$\text{B. f(x) = }2\times 3^x$

The parent function can be exponential in this case but in this case it is translated so the translated function cannot be a parent function.

$\text{C. f(x) = }2\times e^{2x}$

The parent function can be exponential in this case but in this case it is translated so the translated function cannot be a parent function.

$\text{D. f(x) = }e^{x}$

In this case the exponential is the parent function because it is not translated instead it is in its base form.

Therefore, The correct option is D
