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

domain

f (x) = \frac{x + 3}{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{x ^{6}}{x ^{4} + 5}

4 x^{3} - 33 x^{2} + 84 x - 60

f (x) = - 4 x + 12

6 x^{2} sin (x) tan (x)

y = - 7

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