A labelled graph should be drawn in a bell-shaped curve with the following parts:
Y-axis showing “Acceptance (Measured in Sales Volume)”.
X-axis with sections showing Introductory Phase, Acceptance Phase and Rejection Phase.
A label on the graph saying, “Fashion Cycle” and the different stages marked with a rise, peak and decline in the curve
Note: For Visually Impaired Candidates, no need to draw graph/diagram in part (ii)
A racing track is built around an elliptical ground whose equation is given by \[ 9x^2 + 16y^2 = 144 \] The width of the track is \(3\) m as shown. Based on the given information answer the following: 
(i) Express \(y\) as a function of \(x\) from the given equation of ellipse.
(ii) Integrate the function obtained in (i) with respect to \(x\).
(iii)(a) Find the area of the region enclosed within the elliptical ground excluding the track using integration.
OR
(iii)(b) Write the coordinates of the points \(P\) and \(Q\) where the outer edge of the track cuts \(x\)-axis and \(y\)-axis in first quadrant and find the area of triangle formed by points \(P,O,Q\).
