domain of f(x)=arccos(x/2+1)

domain

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

- 4 \leq x \leq 0

Interval Notation

[- 4, 0]

Solution steps

Find known functions domain restrictions:

- 4 \leq x \leq 0

The function domain

- 4 \leq x \leq 0

f (x) = \frac{2 x - 8}{9 x + 54}

f (x) = \frac{- 3}{x - 5}

3 - 1 (x - 1)^{- 1}

f (x) = \frac{7}{x ^{2}}

2 x - 12
