Question

the number y of calories burned after x hours of rock climbing is represented by the linear function y=650x find the domain , is the domain descents or continuous? explain

Answer 1

Answer:

The domain is discrete

Step-by-step explanation:

Given

$y = 650x$

Required

What type of domain is it?

Based on the given options, the domain is continuous.

From the question, we understand that x represents the hours spent in climbing the rock.

The climber can decide to climb for 1 hour, 2 hours, ½ hour, ⅓ hour, ¼ hour, etc..

A domain is said to be discrete if it can only take integers (i.e. whole numbers), if otherwise, it is continuous;

So, since x is not limited to only whole numbers, then we can conclude that the domain of x is continuous
