domain of f(x)=(x+8)/(x-7)

domain

f (x) = \frac{x + 8}{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

f (x) = \frac{( 4 x - ln ( 3 x ) )}{x}

f (x) = arccos (e^{x} - 1)

f (x) = \frac{x + 9}{x ^{2} + 2 x + 1}

\frac{5 x}{3 x - 8}

f (x) = lo g_{4} (x + 6)

What is the domain of f(x)=(x+8)/(x-7) ?
The domain of f(x)=(x+8)/(x-7) is x<7\lor x>7
