Question

2. What are the values where f(t)=0f(t)=0 (also known as the x intercepts) and what do they mean in the context of the dolphin jumping?

Answer 1

1. When f(t) = 0:

t = 5.2, 15.2

2. The x-intercepts (5.2, 15.2) mean that when 5.2 or 15.2 seconds have elapsed, the dolphin is at 0 feet, or the surface of the water.
