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

domain

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

- 3 \leq x \leq 1

Interval Notation

[- 3, 1]

Solution steps

Find known functions domain restrictions:

- 3 \leq x \leq 1

The function domain

- 3 \leq x \leq 1

x^{3} + (4 x^{2} + 17 x - 15)

f (x) = \frac{x + 5}{x - 6}

f (x) = x - 4 - 2

- 5^{x}

f (x) = \frac{x}{( x - 2 )}
