Consider the graph of y 2Vx between x 0 to x 9 and the graph of the vertical line x= 9 as shown below. A region is bounded above by the curve y = 2 x, below by the x axis and on the right by the vertical line x = 9. Your task is to find a formula, in terms of x, which gives the area of a rectangle which will fit in the region so that one side is on the x-axis, one side is on the vertical line x = 9, and one corner is on the graph of y = 2V as shown in the diagram below.

Question
Consider the graph of y 2 x between x 0 to x = 9
and the graph of the vertical line x = 9 as shown below.
A region is bounded above by the curve y = 2Vx , below by the x axis
and on the right by the vertical line x = 9. Your task is to find a formula, in
terms of x, which gives the area of a rectangle which will fit in the region
so that one side is on the x-axis, one side is on the vertical line x = 9,
and one corner is on the graph of y = 2Vx as shown in the diagram
below.
y= 2Vx

Find a formula 'A(x), for the area of the rectangle.
O A (x) = 2/x (9 – x)
O A (x) = 2x (x +9)
%3D
O A (x) = 2x/x
%3D
O A (x) = 2x (x - 9)
