Let me ask you a question: Is square root a function?If we say the codomain (the possible outputs) is the set of real numbers, then square root is not a function! ... is that a surprise?The reason is that there could be two answers for one input, for example f(9) = 3 or -...

To find the domain and range of the function f(x)=√16−x2, we will follow these steps: Step 1: Determine the DomainThe expression under the square root must be non-negative for the function to be defined. Therefore, we need to solve the inequality: 16−x2≥0...

Root-mean-square energy (RMS)—RMS analysis takes the root-mean-square of all samples in a frame [8]. The root-mean-square energy of each frame can be computed separately using Eq. (10.2): (10.2)RMSt=1N·∑k=t·Nt+1·N−1sk2 where RMSt denotes the root-mean-square energy of ...
To find the domain of the function f(x)=1√x2−x−2, we need to ensure that the expression inside the square root is positive, as the square root must be defined and cannot be zero (since it is in the denominator). Here are the steps to determine the domain: Step 1: Set the...
It also calls for Domain name system (DNS), which refers to the host name in a hierarchy of name servers. There can be different domains and there be branches like tree. DCS is configured as a domain, when there are large nos. of users/computers. For domain configuration there will a ...
