domain of f(x)=arccos(x/5)

domain

f (x) = arccos (\frac{x}{5})

- 5 \leq x \leq 5

Interval Notation

[- 5, 5]

Solution steps

Find known functions domain restrictions:

- 5 \leq x \leq 5

The function domain

- 5 \leq x \leq 5

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

m = \frac{3}{2}, (- 2, 0)

f (x) = \frac{3}{5} x^{3} - 10, x = 4

\frac{1}{x + 2}

f (x) = 5 lo g_{4} (x)

What is the domain of f(x)=arccos(x/5) ?
The domain of f(x)=arccos(x/5) is -5<= x<= 5
