Question

find domain of f(x) = (x² + x + 1)^-3/2​

Answer 1

Answer:

Given,

f(x)=x2+x−6x2−3x+2

x2+x−6=0

roots of above equation are: 

x=−3,2

So, x can't be equal to −3or2

The above points are undefined

The function domain is 

x<−3,−3<x<2,x>2

{x:x∈R,x=2,x=−3}

Answer 2

Answer:

It's right mate which is written above... xd... ..☺☺❤❤✌
