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

domain

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

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

f (x) = lo g_{2} (\frac{1}{x})

f (x) = 2 \cdot x^{3} - 4 \cdot x^{2} + \frac{8}{3}

y = tan (t)

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

\frac{1}{f}
