Answer 1

The domain is [2,6] and the range is  [-2,0].

What is the Domain and Range of a Function?

The Domain is all the possible input values to the function, while the range is all the possible values a function can have as an output.

The parabola has endpoints of (2,-2) and (6,-2).

The vertex is (4,-6)

The domain is [2,6]

The range is [-2,0]

Therefore, the domain is [2,6] and the range is  [-2,0].
