Question

what interval does this graph show?

(-infty, -8)
-8, infty)
(-infty, -8
(-8, infty)

Explanation:

Step1: Analyze the graph's open circle

The open circle at -8 means -8 is not included in the interval.

Step2: Analyze the direction of the arrow

The arrow points to the right (towards positive infinity), so the interval starts from -8 (not included) and goes to infinity.

Step3: Determine the interval notation

An open circle at -8 and arrow to the right corresponds to the interval \((-8, \infty)\).

Answer:

D. \((-8, \infty)\)
