Question

Determine the domain and range of:

y = 5 – [1/ (1 + x)]

So, would the domain be all real numbers except -1? And would the range be all real numbers except zero? I'm really confused. . .

Answer 1

Domain is correct. Range is all real numbers except 5. Since 1/(1+x) can never be 0, the equation will never be 5. Write back if you still have questions.

Answer 2

ok thank you!
