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

domain

\frac{2 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

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

y - 6 x = 9

(3, 5), (- 5, 8)

2 - sin (3 x - \frac{π}{5})

f (x) = \frac{2}{3 x - 5}
