domain of f(x)=(3x^2-2)/(x^2-25)

domain

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

ln (\frac{1}{1 - x})

f (x) = \frac{4 x}{10 - 2 x - 46}

f (x) = \frac{2100 + 8 x}{1 + 0.5 x} + 150

f (x) = e^{8 x + 5}

What is the domain of f(x)=(3x^2-2)/(x^2-25) ?
The domain of f(x)=(3x^2-2)/(x^2-25) is x<-5\lor-5<x<5\lor x>5
