Question

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

Answer 1

The expression \( f(0) = 2.7 \) indicates that at the time of the probe's launch (which is \( x = 0 \) days), the distance of the probe from Neptune is 2.7 billion miles. This means that when the probe is initially launched from Earth, it is 2.7 billion miles away from Neptune.
