domain of sqrt(x)-ln(x)

domain

x - ln (x)

x > 0

Interval Notation

(0, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 0

Find positive values for logs:

x > 0

Combine real regions and undefined points for final function domain

x > 0

\frac{2}{∣ x - 2 ∣}

f (x) = 1 - 4 cos (x)

f (x) = 3 x^{2} + 15 x + 18

- 3 tan (3 x + π)

\frac{x + 4}{x ^{2} + x - 3}
