C. At the end of yoga class, Bristol’s heart rate turned to hee resting heart rate
D. The Graph that models Bristol’s heart rate is a parabola.
Step-by-step explanation:
The maximum rate was 120 because that was the highest it went and was the vertex of the parabola. Also the parabola is a maximum.
At the end of yoga class Bristol’s heart rate went back to her resting heart rate because before she started the yoga she had 70 bpm and after the yoga she had 70 bpm. She had the same heart beat before she started the yoga and after.
The graph is a parabola because it has a vertex, it opens downwards, and bc it has a vertex.
