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

domain

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

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

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 2, x = - 2

The function domain

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

d = \frac{4300 x}{x ^{2} + 40}

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

f (x) = lo g_{3} (1 - x) - 3

f (x) = \frac{( x - 3 )}{x ^{2} + 6 x + 9}
