domain of f(x)=cos(arccos(x))

domain

f (x) = cos (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

f (x) = \frac{8}{( x - 4 ) ^{2}}

1 - \frac{2}{x}

f (x) = \frac{2 x ^{2} - 3 x}{x ^{2} - x - 12}

f (x) = 35 + 2 e^{- 2 x + 3}

\frac{x ^{2}}{- x + 8}

What is the domain of f(x)=cos(arccos(x)) ?
The domain of f(x)=cos(arccos(x)) is -1<= x<= 1
