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

domain

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

x < 7 or x > 7

Interval Notation

(- \infty, 7) \cup (7, \infty)

Solution steps

Find undefined (singularity) points:

x = 7

The function domain

x < 7 or x > 7

\frac{2 x ^{2} + 6 x + 5}{x ^{2} + 3 x + 2}

f (x) = 2 x + 4

y = arcsin (x) + π

f (x) = (x) = x

\frac{5}{1 + x ^{2}}

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