Question

A probe is being launched from Earth to gather data about Neptune's atmosphere. The function "f" ( "x" )f(x) gives the probe's distance from Neptune "x"xdays after launch. The distance is measured in billions of miles. What does "f" ( 0 ) equals 2.7f(0)=2.7 tell you?

Answer 1

The notation "f(0) = 2.7" indicates the distance of the probe from Neptune at the moment of launch (0 days after launch). Since the distance is measured in billions of miles, this means that at launch, the probe is 2.7 billion miles away from Neptune. This provides a reference point for understanding how the probe's distance from Neptune changes over time as it travels through space.
