domain of f(x)=-(x^2-50)/(x^2-25)

domain

f (x) = - \frac{x ^{2} - 50}{x ^{2} - 25}

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

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 5, x = - 5

The function domain

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

f (x) = 2 - x - 2

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

ln (x^{2} - 3 x - 18)

x + \frac{1}{x + 1}

f (x) = - 8 x^{2} + 3

What is the domain of f(x)=-(x^2-50)/(x^2-25) ?
The domain of f(x)=-(x^2-50)/(x^2-25) is x<-5\lor-5<x<5\lor x>5
