Question about math

Question

A comet is travelling through the solar system. It passes by the Earth before curving around the Sun and heading back out into deep space. The distance of the comet from Earth, y, is tracked by satellite telescopes and is expressed as a function of time,x, since the comet was first spotted

A:state the domain of the function

B:The satellites detect, that at its closes points, the comet was a distance of 0.14 AU from Earth. State the range of the functions

Answer 1

Hello, I hope you're doing well. This sounds more like a physics problem which would need the time spent passing earth and the sun as a given.

If just math, the domain of X would be (0, infinity) with 0 being the start of the time tracked when the comet was first spotted and infinity to represent the comet drifting out endlessly, assuming nothing stops it.

Again, if no other information is given, the range of y is (0.14, infinity) assuming the units are AU. THe problem states 0.14 AU is the closest the comet gets to the earth, and the comet drifting infinitely into space afterward would make it infinitely far away from earth as well.

Let me know if that helps or if you have any more questions, thank you.
