domain of f(x)=(-2)/(x^2+2x-35)

domain

f (x) = \frac{- 2}{x ^{2} + 2 x - 35}

x < - 7 or - 7 < x < 5 or x > 5

Interval Notation

(- \infty, - 7) \cup (- 7, 5) \cup (5, \infty)

Solution steps

Find undefined (singularity) points:

x = 5, x = - 7

The function domain

x < - 7 or - 7 < x < 5 or x > 5

f (x) = \frac{ln ( x - 1 )}{x ^{3} - 2 x}

f (x) = e^{x} + 2 x

\frac{1 - 10 a + 25 a ^{2}}{5 a - 1}

f (x) = x^{2} - 9 x - 36

7 x + 4

What is the domain of f(x)=(-2)/(x^2+2x-35) ?
The domain of f(x)=(-2)/(x^2+2x-35) is x<-7\lor-7<x<5\lor x>5
