What are the domain and range of this function?
Arlecino [84]

Answer:

Correct answer:  The third answer is correct

Step-by-step explanation:

The domain of each function is defined by observing the behavior of the function from left to right by following the growth of numbers on the x axis of real numbers.

In the same way, the range of each function is defined by observing the behavior of the function from the bottom y axis upwards by following the growth of numbers on the y axis of real numbers.

The given function extends from negative infinite to positive infinite on the x axis and that is the domain of this function.

The minimum of a given function is 4, which means that the function exists from 4  upwards and that is the range of the function.

Domain; all real numbers or x ∈ ( -∞ , + ∞)

Range:  ( y ≥ 4 )
