domain of f(x)=(3x-9)/(x^2-6x+9)

domain

f (x) = \frac{3 x - 9}{x ^{2} - 6 x + 9}

x < 3 or x > 3

Solution steps

Find undefined (singularity) points:

x = 3

The function domain

x < 3 or x > 3

f (x) = \frac{3}{5} x - 12

\frac{2 x ^{2} + 16 x - 18}{x ^{2} + x - 6}

3 cos (x - \frac{π}{4}) - 1

f (x) = x^{4} - 50 x^{2} + 4

f (x) = 2 x - 4

What is the domain of f(x)=(3x-9)/(x^2-6x+9) ?
The domain of f(x)=(3x-9)/(x^2-6x+9) is x<3\lor x>3
