domain of f(x)=(3x^2-2x-1)/(x^2+3x-10)

domain

f (x) = \frac{3 x ^{2} - 2 x - 1}{x ^{2} + 3 x - 10}

x < - 5 or - 5 < x < 2 or x > 2

Interval Notation

(- \infty, - 5) \cup (- 5, 2) \cup (2, \infty)

Solution steps

Find undefined (singularity) points:

x = 2, x = - 5

The function domain

x < - 5 or - 5 < x < 2 or x > 2

sec (3 x)

f (x) = - \frac{7}{2 t t}

f (x) = 1 - 1

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

f (x) = \frac{( x + 8 )}{x - 8}

What is the domain of f(x)=(3x^2-2x-1)/(x^2+3x-10) ?
The domain of f(x)=(3x^2-2x-1)/(x^2+3x-10) is x<-5\lor-5<x<2\lor x>2
