Question

find domain and range of following functions
(i)f(x)=1/x-2
​

Answer 1

Step-by-step explanation:

Put denominator equal to zero

x-2=0

x=2

Domain is defined at set of all real numbers expect 2

domain of function is (-infinity,2)U(2,+infinity)

Range of function is (-infinity,0)U(0,+infinity)
