domain of f(x)=(x-8)^{1/2}

domain

f (x) = (x - 8)^{\frac{1}{2}}

x \geq 8

Interval Notation

[8, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 8

The function domain

x \geq 8

\frac{6 x - 5}{x + 9}

(- 5, 5), (2, 2)

ln (ln (ln (4 x)))

y = \frac{x}{x ^{2} - 4}

f (x) = y^{2} + 2 x - x^{2} y^{2} = 0
