Question 27

The graph shows part of the curve with equation y=54x2+2x\displaystyle y = \frac{54}{x^2} + 2xy=x254​+2x

A coordinate diagram showing the axes, curve C, point P(3, 12), line l, vertical line x = 1, and shaded region R.

P(3,12)P(3, 12)P(3,12) lies on CCC. Line l l\,l is the normal to C C\,C at PPP. Region R R\,R is bounded by the curve CCC, the line l l\,l and the line with equation x=1x = 1x=1.

Find the exact area of RRR.
