Answer:

  • Increasing x > -1; Decreasing x < -1

Step-by-step explanation:

"increasing" means the graph goes upward to the right. This graph only does that for x > -1.

"decreasing" means the graph goes downward to the right (or upward to the left). This graph only does that for x < -1.

____

Your problem statement indicates you know the vertex is at x=-1. Any change in direction occurs there, eliminating the 2nd and 4th choices. After you figure that out, you just need to match "rising (/)" or "falling (\)" with "greater than (>)" or "less than (<)".
