domain of f(x)= 1/((x-3))

domain

f (x) = \frac{1}{( 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

y + 6 = \frac{1}{3} (x - 4)

f (x) = 3 x^{3}

f (x) = - x^{3} + 3 x^{2} + 9 x + 1

\frac{5 x}{x ^{2} - 16}

4 x^{3} + 7 x^{2} - 20 x + 9

What is the domain of f(x)= 1/((x-3)) ?
The domain of f(x)= 1/((x-3)) is x<3\lor x>3
