Denise lives in a circular-shaped neighborhood and goes for a walk. The graph displays the distance Denise is from her house. Describe the change in distance from her house over time.

• Denise walks at a constant rate toward her house. Then she walks at a constant rate away from her house.

• Denise is at her house. Then she walks at a varied rate away from her house. Then she reaches the halfway point opposite her house. Then she walks at a varied rate toward her house. Finally, Denise reaches home.

• Denise is at her house. Then she walks at a constant rate away from her house. Then she reaches the halfway point opposite her house. Then she walks at a constant rate toward her house. Finally, Denise reaches home.

• Denise is at her house. Then she walks at a constant rate away from her house. Then she reaches the halfway point opposite her house. Then she walks at a constant rate away from her house.
