domain of (2x^2-1)/5

domain

\frac{2 x ^{2} - 1}{5}

- \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

y = \frac{1}{x - 2} + 1

lo g_{2} (x + 2) - 3

f (x) = \frac{x + 4}{x ^{2} + 64}

f (x) = e^{x} 2 x

3 - 6 sin (2 x + \frac{π}{2})
