domain of g(x)=(7x)/(x^2-4)

domain

g (x) = \frac{7 x}{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

\frac{3}{4} x + 2

y = \frac{x + 9}{x ^{2} - 81}

y = arcsin (\frac{1}{x})

f (t) = 4 - x

\frac{2 x ^{2} + 2 x - 12}{x ^{2} + 4 x - 5}
