domain of f(x)=(4x^2+4)/(2x^2-8)

domain

f (x) = \frac{4 x ^{2} + 4}{2 x ^{2} - 8}

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

3 - t

y = \frac{8}{x}

(x + 1)^{2} - 3

\frac{7}{2 7 x + 8}

g (x) = \frac{3 x}{x ^{2} - 4}
