If |Z+5|≤7, then find the maximum and minimum value of |Z+2|

|Z+5|<7

-7 < Z+5 < 7 

-12 < Z < 2

:. -10 < Z+2 < 4

so, minimum value  = -10

and maximum value = 4

Approved

Dear Student,

Using the property,

||z₁| - |z₂|| ≤ |z₁+z₂| ≤ |z₁| + |z₂|

and

 ||z₁| - |z₂|| ≤ |z₁-z₂| ≤ |z₁| + |z₂|

we can evalute the answer.

Best Of luck

Plz Approve the answer...!!!!
