domain of f(x)=(x+7)/(x-3)

domain

f (x) = \frac{x + 7}{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

\frac{x - 5}{x ^{2} - 4}

f (x) = x^{2} - 5 \cdot x - 4

lo g_{10} (x^{3} - 6 x^{2} + 3 x + 10)

y = 2 x^{5} - 3 x^{4} + 5 x - 8

- x - 5 + 4

What is the domain of f(x)=(x+7)/(x-3) ?
The domain of f(x)=(x+7)/(x-3) is x<3\lor x>3
