domain of (e^{2x}-1)/(1+e^{2x)}

domain

\frac{e ^{2 x} - 1}{1 + e ^{2 x}}

- \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

3^{x} - 3

\frac{ln ( x ^{2} - x )}{- x}

f (x) = \frac{x + 5}{( x + 8 ) ( x - 9 )}

tan (2 t)

2 x^{2} - 12 x + 9
