Problem 4. Given a continuous function f over some region R with finite nonzero area, we can interpret the double integral as follows /| f(r, y) dA = F · |R| where f is the average value of f over the region R and |R| is the area of the region R. r? + 7y over R Using the above interpretation of a double integral, find the average value of f(x,y) {(r, y) |0
