domain of f(x)=(x-8)/(x^2-17x+72)

domain

f (x) = \frac{x - 8}{x ^{2} - 17 x + 72}

x < 8 or 8 < x < 9 or x > 9

Interval Notation

(- \infty, 8) \cup (8, 9) \cup (9, \infty)

Solution steps

Find undefined (singularity) points:

x = 9, x = 8

The function domain

x < 8 or 8 < x < 9 or x > 9

f (x) = 50 e^{0.1 x}

\frac{x - 1}{x ^{2} - x - 6}

2^{x - 4}

f (a) = a

f (x) = x^{2} - 2 x - 1

What is the domain of f(x)=(x-8)/(x^2-17x+72) ?
The domain of f(x)=(x-8)/(x^2-17x+72) is x<8\lor 8<x<9\lor x>9
