Question

What is domain of function f(x) = x-1 for it to be defined everywhere on domain?(2,00)(-00,00) - {0}[0,00)None of the mentioned​

Answer 1

So, the domain of f(x) = x-1 will be x = x-1

Step-by-step explanation:

By the rule x+1 = x-1

if f(x) = x-1 then x = x-1÷f

So, x = x-1÷f then

(x-1÷f)-1÷f

=x+[(-1) - ( -1)] ÷[f÷f] (By distributive property)

=x+(-2)÷1

=x+(-2)

=x-2

f = (x-2)

(x-2) × (x) = x-1

= (x×x) - 2 = x-1

=2x-2= x-1

= x = x-1
