The region R will be the area of the triangle formed from the x-axis, the line and the point P

#
  • the area of the rectangle between the curve and point P
#
  • the integral of the curve between 2 and P
#

the line y = 6 intersects at x=2 and x=4 so it is a rectangle

Btw what is a normal

#

💀

wet bobcat
#

negative recipicol gradient

#

of the tangent

#

a normal is perpendicular to the tangent

Intergrated the curve C equation with the limit of 4 to 2

#

Then deferentiate the curve c to get the radient and since C is normal to get the gradient of l used the formula M1 x M2 =-1
