Answer 1

Answer:

Step-by-step explanation:

The Root Mean Square (RMS) of a function f over a specified interval [a,b] is the square root of the arithmetic mean (average) of the squares of the original values. Substitute the actual values into the formula for the root mean square of a function. Evaluate the integral. Let u=x−2 u = x - 2 .
