The domain is the set of all numbers between the left parenthesis and the comma: {6, -8, 4, 3}

The range is the set of all numbers between the comma and the right parenthesis: {-5, -4, 3, 4}

_____
The order of the numbers in the set does not matter. Conventionally, they are sorted smallest to largest just to make set operations easier. Here, I have left them in the order in which the relation is defined.

A polynomial function has a root of -5 with multiplicity 3, a root of 1 with multiplicity 2, and a root of 3 with multiplicity 7

Answer:

The graph of the function is negative on (3, ∞)

Step-by-step explanation:

The function starts negative at the left side of the graph, crosses the x-axis at x = -5, touches the x-axis at x = 1, again crosses into negative values at x = 3.

The function is positive on the open intervals (-5, 1) and (1, 3). It is negative on the open intervals (-∞, -5) and (3, ∞). The latter description matches the last answer choice:

the graph of the function is negative on (3, ∞).
