Question

determine the domain of the function graphed below. options: (-1, 9), -1, 4, -1, 9, (-1, 4)

Explanation:

Step1: Identify the leftmost x - value

The leftmost point of the graph has an x - coordinate of - 1. Since the point is a closed dot, - 1 is included in the domain.

Step2: Identify the rightmost x - value

The rightmost point of the graph has an x - coordinate of 9. Since the point is a closed dot, 9 is included in the domain.

Step3: Determine the domain interval

The domain of a function is the set of all x - values for which the function is defined. From the graph, the x - values range from - 1 (inclusive) to 9 (inclusive). So the domain is \([-1,9]\).

Answer:

\([-1, 9]\) (corresponding to the option \([-1, 9]\))
