Summary: MIN is not correct

Initial Comment:
I have the following problem with MIN : the graph of min 
below does not match the min of the curves on the second 
graph. 
 
session: 
f(h,k,l):=(h^k)*((1/h)*k*(1+l)+(d-k)*2*l); 
g(h,k,l):=2*d*l+(h^k)*((1/h)*k*(1-l)-(d-k)*2*l); d:2; l:0.5; 
plot2d([f((1-v)^(1/2),2,l), f((1-v),1,l), g(v^(1/2),2,l), g(v,1,l)], 
[v,0,1])$  
plot2d(min(f((1-v)^(1/2),2,l), f((1-v),1,l), g(v^(1/2),2,l), g(v,1,l)), 
[v,0,1])$
