domain of f(x)=(x-7)/(x-4)

domain

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

x < 4 or x > 4

Interval Notation

(- \infty, 4) \cup (4, \infty)

Solution steps

Find undefined (singularity) points:

x = 4

The function domain

x < 4 or x > 4

(100, 32.5), (300, 39.5)

\frac{2}{\frac{9}{x} + 5}

m = 3, (- 9, 2)

3 x + 5

f (x) = x + 4 - 3

What is the domain of f(x)=(x-7)/(x-4) ?
The domain of f(x)=(x-7)/(x-4) is x<4\lor x>4
