domain of f(x)=arccos(x)

domain

f (x) = arccos (x)

- 1 \leq x \leq 1

Interval Notation

[- 1, 1]

Solution steps

Find known functions domain restrictions:

- 1 \leq x \leq 1

The function domain

- 1 \leq x \leq 1

d o main f (x) = \frac{2 x ^{3} - 250}{x ^{2} - 2 x - 15}

cr i t i c a l f (x) = \frac{x}{x ^{2} - 1}

in v erse f (x) = \frac{x + 20}{x - 5}

r an g e f (x) = x^{2} - 10 x + 16

d i s t an ce (5, 3), (4, 6)
