domain of 1/3 arccos(x/4-2)

domain

\frac{1}{3} arccos (\frac{x}{4} - 2)

4 \leq x \leq 12

Interval Notation

[4, 12]

Solution steps

Find known functions domain restrictions:

4 \leq x \leq 12

The function domain

4 \leq x \leq 12

f (x) = \frac{x ^{2} - 3 x - 4}{x + 1}

ln (1 - t^{2})

h (x) = \frac{x + 8}{x ^{2} - 64}

f (x) = 1 - ∣ 3 x + 2 ∣

f (x) = 3 + 2 x - 1
