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

domain

\frac{x + 2}{x ^{2} - 3 x - 10}

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

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 5, x = - 2

The function domain

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

f (y) = \frac{1}{( y - 2 ) + ( y - 8 )}

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

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

\frac{- 1}{2 5 - x}

f (x) = 1 - \frac{9}{x ^{2}}
