domain of f(x)= 6/(x^2-21x+98)

domain

f (x) = \frac{6}{x ^{2} - 21 x + 98}

x < 7 or 7 < x < 14 or x > 14

Interval Notation

(- \infty, 7) \cup (7, 14) \cup (14, \infty)

Solution steps

Find undefined (singularity) points:

x = 14, x = 7

The function domain

x < 7 or 7 < x < 14 or x > 14

f (x) = \frac{x + 3}{x + 4}

16 - 2 x - x^{2}

e^{- 7 x}

f (x) = x^{3} - 5

f (x) = \frac{2 ( x + 6 )}{3 x}

What is the domain of f(x)= 6/(x^2-21x+98) ?
The domain of f(x)= 6/(x^2-21x+98) is x<7\lor 7<x<14\lor x>14
