The average value of f over the region D is 243/4
To answer the question, we need to know what the average value of a function is
<h3>What is the average value of a function?</h3>The average value of a function f(x) over an interval [a,b] is given by
Now, given that we require the average value of f(x,y) = 3xy over the region D where D is the triangle with vertices (0, 0), (1, 0), and (1, 9).
x is intergrated from x = 0 to 1 and the interval is [0,1] and y is integrated from y = 0 to y = 9
So,
So, the average value of f over the region D is 243/4
