Question

the domain of y=1/x+8-1 is all real number except x=-1.
true or false?

Answer 1

Does the function look like this \[\Large y = \frac{ 1 }{ x + 8} - 1\]? OR

Answer 2

yes

Answer 3

\[\Large y = \frac{ 1 }{ x } + 8 - 1\]?

Answer 4

first one

Answer 5

The denominator cannot go to zero because you cannot divide by 0.
So (x + 8) should not go to 0. That means x should not be -8.

So the domain is all real numbers except x = -8.

Answer 6

thank you!
