Question

State the domain of the function: f(x)=(x^2+1)/(x^2-3x)

Answer 1

well there are restrictions in the denominator... can you identify them..?

Answer 2

0, obviously.

Answer 3

3, I'm thinking.

Answer 4

Yes, three and nine.

Answer 5

Oops, sorry. Zero and three, I mean.

Answer 6

there are only 2...0 and 3

\[x^2 - 3x = x(x - 3)\]

so the domain is all real x except.... x = 0 and x = 3
