Find the range of the following piecewise function. [2,16) (2,16] [2,∞) (2,∞)

Range is the set of possible values of y in the ordered pairs.

the piecewise function has possible values
2, 7+ to 11- and 16 to ∞
which can be written as
{2 ∪ (7,11) ∪ [16,∞)}
in interval notation.

I think the answer choices you posted correspond to another problem.
