domain of f(x)=(28)/(x^2+7x-98)

domain

f (x) = \frac{28}{x ^{2} + 7 x - 98}

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

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 7, x = - 14

The function domain

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

\frac{5 x}{4 x - 2}

x + 2 - 2 x + 3

f (x) = - 4 lo g_{10} (x + 2)

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

\frac{16 - x ^{2} - 4}{2 - ∣ x - 3 ∣}

What is the domain of f(x)=(28)/(x^2+7x-98) ?
The domain of f(x)=(28)/(x^2+7x-98) is x<-14\lor-14<x<7\lor x>7
