Question

THE MINIMUM VALUE OF EXPRESSION (P+1/P)=??

Comments

it will be -infinity , if there is no condition on p

---

NOPES. ITS 2 WHEN P=1.

---

which is minimum -infinity or 2 ?

Answer 1

at two point 0-h and (-infinity).

this function is only not defined at p=0

in p from (0,1] it is decrease (1,inf) it start to increase.

so it will give minimum 2 only when p is positive.

but as here p's domain not specified so we take also negative value.

so it will give min value at  0-h and -infinity.

Answer 2

it depends on the value of p
