The domain of the function is -1 ≤ x ≤ 3 or x ∈ (-1, 3) option (D) is correct.
What is a function?
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a graph of a function shown in the picture.
The graph starts at x = -1 and goes upto x = 3
The function only exists between the interval (-1, 3)
The domain of the function -1 ≤ x ≤ 3
Thus, the domain of the function is -1 ≤ x ≤ 3 or x ∈ (-1, 3) option (D) is correct.
