Answer:
The domain is discrete
Step-by-step explanation:
Given
Required
What type of domain is it?
<em>Based on the given options, the domain is continuous.</em>
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
Answer:
If you write a number as a fraction, that number's reciprocal is a fraction with the numerator and the denominator switched around. For example, the reciprocal of
4
5
is
5
4
. Some general rules to keep in mind:
-If the fraction has a
0
in the numerator, the reciprocal is undefined.
-If the fraction has a
0
in the denominator, the fraction itself is undefined. Thus it can't have a reciprocal.
-Any other fraction has exactly one reciprocal.
Finally, the reciprocal of a reciprocal is the original fraction. This means if you flip a fraction's numerator and denominator, and then flip them back, you get the number you started with.
