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

Answer 1

\[\frac{x-1}{(x+1)(x-1)}={x+1}\]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)

Answer 2

he is right

Answer 3

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

Answer 4

skateboarder what do you mean?

Answer 5

Range should be all real numbers

Answer 6

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

Answer 7

HELOOOOOOOOOOOOO?
