3540 The average value or mean value of a continuous functionf(x, y) over a rectangle R
Chapter 14, Problem 36(choose chapter or problem)
The average value or mean value of a continuous function \(f(x, y)\) over a rectangle \(R=[a, b] \times[c, d]\) is defined as
\(f_{\mathrm{ave}}=\frac{1}{A(R)} \iint_{R} f(x, y) d A\)
where \(A(R)=(b-a)(d-c)\) is the area of the rectangle \(R\) (compare to Definition 5.8.1). Use this definition in these exercises.
Find the average value of \(f(x,y)=x^{2}+7y \) over the rectangle \({[0,3] \times[0,6]}\).
