Question

determine the domain of the following graph:
(graph of a function with an open circle at (-11, -2) and an open circle at (11, 0), passing through (0, -3) and intersecting the x-axis at (3, 0) and (11, 0) with a peak around x=7)
answer attempt 2 out of 3

Explanation:

Step1: Identify left boundary

The leftmost point has an open circle at \( x = -11 \), so the domain starts just above \( -11 \).

Step2: Identify right boundary

The rightmost point has an open circle at \( x = 11 \), so the domain ends just below \( 11 \).

Step3: Determine interval

The domain is all \( x \) such that \( -11 < x < 11 \), written as \( (-11, 11) \).

Answer:

\( -11 < x < 11 \) (or in interval notation \( (-11, 11) \))
