Answer: y ≥ -6
The vertical bar means "such that".
Step-by-step explanation
The range is the set of possible y outputs. The lowest we can go on this V shape graph is when y = -6. We can go forever upward.
Either y = -6 or y > -6. Those combine to y ≥ -6
Side note: That inequality in bold translates to the interval notation [-6, ∞)
