Concept explainers
(a)
To calculate: To find the domain of the function and find whether domain is discrete or continuous
(a)
Answer to Problem 36E
Domain of function is
Domain is continuous
Explanation of Solution
Given: The number
Formula Used:
Domain of a function is the set of all possible input values. They are of two types:
A discrete domain is a set of input values that consists of only certain numbers in an interval. Graph of discrete domain are scattered points
A continuous domain is a set of input values that consists of all numbers in an interval. Graph of continuous domain has lines or curves
Calculation:
Given that number
Since number of hourscan be represented in decimal, thus domain for the function is
Domain is continuous domain
Conclusion:
Hence,
(b)
