What is the domain of the function f(x) =x+1/
X^2-6x+8?

The domain of the function is all real values of x, except and

Step-by-step explanation:

We are given the following function:

It's a fraction, so the domain is all the real values except those in which the denominator is 0.

Denominator:

Quadratic equation with

Using bhaskara, the denominator is 0 for these following values of x:
