domain of (x^2+4x-5)/(x^2+x-2)

domain

\frac{x ^{2} + 4 x - 5}{x ^{2} + x - 2}

x < - 2 or - 2 < x < 1 or x > 1

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 1, x = - 2

The function domain

x < - 2 or - 2 < x < 1 or x > 1

(- 2, 2), (2, - 8)

(x - 1)^{2} + 4

\frac{x}{1 - x}

e^{- 1.5 x^{2}}

3 - e^{2 x}
