(1.)Find the DOMAIN and RANGE of f.
f(x)= x-1/x^2-1

(2.)Find the DOMAIN of f.
f(x)= sq root of x-2 / x^2-x

Question

(1.)Find the DOMAIN and RANGE of f.
f(x)= x-1/x^2-1

(2.)Find the DOMAIN of f.
f(x)= sq root of x-2 / x^2-x

anonymous · Answer

$$\frac{x-1}{(x+1)(x-1)}={x+1}$$so long as 
$$x\neq 1$$ so domain is all real numbers except 1 and range is all real numbers except 2
(since x cannot be 1, x+1 cannot be 2)

he is right

anonymous · Answer

Satellite shouldn't the simplification be 1 / x + 1 so the domain is all real numbers but x cannot equal -1

skateboarder what do you mean?

anonymous · Answer

Range should be all real numbers

anonymous · Answer

just to clarify..
1) domain: all real numbers, except for 1
     range:all real numbers except 2
2) what is the domain?
