domain of f(x)= 3/(x^2+2x-35)

domain

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

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

f (x) = 4 - 2 x^{2}

f (x) = x^{4} - 6 x^{2}

f (x) = arccosh (x)

What is the domain of f(x)= 3/(x^2+2x-35) ?
The domain of f(x)= 3/(x^2+2x-35) is x<-7\lor-7<x<5\lor x>5
