To calculate: To find the domain of the function and determine whether the domain is discrete or continuous
Answer to Problem 31E
Domain is a discrete domain
Explanation of Solution
Given: Domain is
Input Time, x | 3 | 6 | 9 |
Output Distance, y | 150 | 300 | 450 |
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:
Domain is given as follows:
Input Time, x | 3 | 6 | 9 |
Output Distance, y | 150 | 300 | 450 |
Here, domain is
Since the graph is scattered, hence the domain is discrete domain.
Conclusion:
Hence, domain is discrete domain.

The growth of bacteria in food products makes it necessary to time-date some products (such as milk) so that they will be sold and consumed before the bacteria count is too high. Suppose for a certain product that the number of bacteria present is given by f(t)=5000.1 Under certain storage conditions, where t is time in days after packing of the product and the value of f(t) is in millions. The solution to word problems should always be given in a complete sentence, with appropriate units, in the context of the problem. (a) If the product cannot be safely eaten after the bacteria count reaches 3000 million, how long will this take? (b) If t=0 corresponds to January 1, what date should be placed on the product?arrow_forward2.6 Applications: Growth and Decay; Mathematics of Finances 1.
