They are not discrete values. The figure below may help you understand the difference between discrete and continuous data? Can there really be any value for time? c) What percentage of shoppers shopped more than four times? However, current popular algorithms to solve them either rely on linear models or unreliable uncertainty estimation in non-linear models, which are required to deal with the exploration-exploitation trade-off. We will also learn how to write the domain and range of these problems! To overcome this problem, researchers rather ask for the range of their income such as $0 to 1,000, $1,000 to $2,500, $2,500 to $5,000, $5,000 or higher. an infinite number of values that it could take on, because You can list the values. And I want to think together In practice, no one compounds interest continuously but it is used extensively for pricing options, forwards and other derivatives. Now, let us look at discrete data definition. For this particular function, it is telling you that at x = 1, the function equals 1. Identify the following, i) Domain .
