domain of f(x)=(x-9)/(x^2-17x+72)

domain

f (x) = \frac{x - 9}{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

lo g_{x + 3} (5)

5 x^{4} - 3 x^{2} + 7

f (x) = \frac{x - 4}{x ^{2} - 7 x + 12}

3.6

f (x) = y - 2

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