Question

What is the domain of y=1+(1/x)+(1/x^2) ?

Answer 1

hint: s cannot be 0

Answer 2

* x cannot be zero

Answer 3

when y=o the -intercepts are imaginary therefore no x-intercept; same for x=o. but if u give any other value to x or y u can solve for one variable therefore the domain will be(\[(-\infty;0)U(0;\infty)\]

Answer 4

another way of stating the domain is all real numbers except 0

Answer 5

exactly
