Q 6
 
Here y = f(x) is a curve.
 
given thatf^{
 
Integrate it w.r.t x
 
u getf^{
 
At (2,1), slope is 3  {As y=3x-5}
 
Thus ,
 
f^{
 
Now integrate again
u get
 
f(x)=x^{3}-3x^{2}+3x+C_{1}
 
As f(x)=3x-5
 
f(2)=1
 
f(2)=2^{3}-3.2^{2}+3.2+C_{1}=1\\\\ C_{1}=-1
 
 
f(x)=x^{3}-3x^{2}+3x-1\\\\ f(x)=(x-1)^{3}
