How do I find the domain and function using this calsulator (web 2.0) to get it in interval notation.
f(x)=(x^2+3)/(x^2-5x+6)
The domain will be all real numbers except where the denominator is zero.
The denominator can be written as (x-2)(x-3) so this is zero when x = 2 and x = 3.
Hence the domain of this function is: x ∈ (-∞, 2)∪(2, 3)∪(3, ∞)
