The appropriate choice is
, meaning that the function's domain is
.
Further details:
In this case, the function is presented as a collection of ordered pairs detailed in Table 1 (included at the end).
The function can generally be expressed as
, with
representing the domain of the function,
being the range and
indicating the set of real numbers.
The domain consists of all points where the function is defined, which includes all potential values of
that yield an output
.
The range refers to all output values of
derived from the specified domain.
The function is
.
For different values of
, the corresponding outcomes for
can be expressed as follows:

Consequently, the domain of the function is
.
Option (A)
In this scenario, the domain is
.
The provided domain is represented in function form where
(domain) corresponds to
and
(range) represents
.
Thus, this representation does not accurately reflect the domain.
The representation corresponds to the ordered pairs that define a function.
Therefore, the option (A) is incorrect.
Option (B)
In this case, the domain is
.
Here, the domain of the function

matches

, which coincides with choice (B).
Thus, the option (B) is correct.
Option (C)
In this example, the domain is
.
And the function's domain

does not align with the choice (C).
Therefore, the option (C) is incorrect.
Option (D)
Here, the domain is
.
The function's domain
does not correspond with option (D).
Thus, the option (D) is incorrect.
The function's domain is
.
Hence, the
option (B) is
correct.
