Question

Identify the asymptotes, domain and range of the function:
f(x)=(1/x)-1

Answer 1

Domain is all the values of x with a defined value of f(x). That means no dividing by 0, no square-rooting a negative number, etc.

Answer 2

The domain is all real numbers _except_ for one. Do you know that one number?

Answer 3

1

Answer 4

?

Answer 5

No. Remember that you can't divide by 0. Let's try 0.
f(0) = (1/0)-1. We're dividing by 0, so 0 isn't in the domain.

Answer 6

oh okay

Answer 7

what about range and asymptotes?

Answer 8

Remember how domain is sort of like all the x-values the function can be? Well, range is like all the f(x)-values the function can be.

Answer 9

oh okay got it thanks

Answer 10

No problem. :)
