Question

doman and range of y= 1/x

Answer 1

domain all real x which does not equal to 0
range all reals except for zero

Answer 2

You cannot divide by zero. So the domain is the set of all real numbers but x cannot equal zero.


Because the horizontal asymptote is y = 0, this means that the range is the set of all real numbers but y cannot equal zero.

Answer 3

i see what u are saying but how would u write that in interval notation which is my biggest issue..

Answer 4

Domain: \[(-\infty,0)\cup(0,\infty)\]

Range: \[(-\infty,0)\cup(0,\infty)\]


Note: in this case, the domain and range are the same. This is not always the case though.
