domain of f(x)=2sqrt(x-6)

domain

f (x) = 2 x - 6

x \geq 6

Interval Notation

[6, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 6

The function domain

x \geq 6

\frac{1}{arccos ( x )}

f (x) = \frac{5 x - 10}{x ^{2} + 5 x - 14}

f (x) = \frac{1}{x ^{2}} - 3

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

f (x) = \frac{2 x + 1}{x + 2}
