domain of f(x)=(8x^2)/(16-x^2)

domain

f (x) = \frac{8 x ^{2}}{16 - x ^{2}}

x < - 4 or - 4 < x < 4 or x > 4

Interval Notation

(- \infty, - 4) \cup (- 4, 4) \cup (4, \infty)

Solution steps

Find undefined (singularity) points:

x = 4, x = - 4

The function domain

x < - 4 or - 4 < x < 4 or x > 4

h (x) = 30 - 5 x

f (x) = 2 + 2 x

y = [\frac{x}{2}]

f (x) = \frac{x ^{3} - 3}{x ^{4} + 1}

(x)
