Question

What are the domain and range of an exponential parent function

Answer 1

Answer: OPTION C

Step-by-step explanation:

An exponential parent function is the simplest form of the exponential function. This is:

$y=b^{x}$

By definition, you have:

- The values of y are positive for all values of x.

- As x increases, the values of y increases too with no bounds.

- As x decreases, the values of y approaches zero.

Therefore, the domain is all real numbers and the range is all positive numbers and never zero.

The answer is the option C.

Answer 2

Answer:

The correct option is (C)

Step-by-step explanation:

The domain of an exponential parent function is the set of all real values of x that will give real values for y in he given function.

On the other hand the range of a function is the set of all real values of y that you can get by plugging real numbers into x in the same function. The line y = 0 is a horizontal asymptotic for all exponential functions. When a > 1: as x increases, the exponential function increases, and as x decreases, the function decreases. So option C is the correct answer.
