domain of f(x)=(x^2-6x+8)/(x-4)

domain

f (x) = \frac{x ^{2} - 6 x + 8}{x - 4}

x < 4 or x > 4

Interval Notation

(- \infty, 4) \cup (4, \infty)

Solution steps

Find undefined (singularity) points:

x = 4

The function domain

x < 4 or x > 4

- lo g_{2} (x - 1)

\frac{5 x}{x - 2}

y = 2 x - ∣ 4 - x ∣

(2 x)^{\frac{1}{3}} - 7

f (x) = \frac{x + 4}{x - 7}

What is the domain of f(x)=(x^2-6x+8)/(x-4) ?
The domain of f(x)=(x^2-6x+8)/(x-4) is x<4\lor x>4
