domain of f(x)=(12-3x^2)/(x-3)

domain

f (x) = \frac{12 - 3 x ^{2}}{x - 3}

x < 3 or x > 3

Interval Notation

(- \infty, 3) \cup (3, \infty)

Solution steps

Find undefined (singularity) points:

x = 3

The function domain

x < 3 or x > 3

f (x) = 3 x (2 - x)

5 x - 2 x^{2} - x - 2

x^{2} + 11 x + 24

lo g_{10} (x^{4})

f (x) = \frac{2}{x ^{2} - 1}

What is the domain of f(x)=(12-3x^2)/(x-3) ?
The domain of f(x)=(12-3x^2)/(x-3) is x<3\lor x>3
