domain of f(x)=(-1+4x)/(x-3)

domain

f (x) = \frac{- 1 + 4 x}{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) = \frac{2 - 7 ( - 2 )}{( - 2 ) - 1}

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

e^{c o s (x)}

\frac{1}{3 x ^{2} + 8}

- x^{2} + 10 x

What is the domain of f(x)=(-1+4x)/(x-3) ?
The domain of f(x)=(-1+4x)/(x-3) is x<3\lor x>3
