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

domain

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

x < - 2 or x > 1

Interval Notation

(- \infty, - 2) \cup (1, \infty)

Solution steps

Find non-negative values for radicals:

x \leq - 2 or x \geq 1

Find undefined (singularity) points:

x = 1, x = - 2

Combine real regions and undefined points for final function domain

x < - 2 or x > 1

f (x) = 200 - \frac{x}{30}

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

f (x) = 2 x + 3, x \geq - 4

x e^{s i n (x)}

f (x) = 2 x + 2, x > 2

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