Formula for curvature for a well behaved curve y=f(x) is
K(x)=
The given curve is y=7
k(x)=
For Maxima or Minima
→
[not possible ∵there exists no value of x satisfying these equation]
→
Solving this we get
x=
As you will evaluate <0 at x=
So this is the point of Maxima. we get y=7×1/√98=1/√2
(x,y)=[,1/√2]
k(x)=
k(x)=
k(x)=0
