domain of f(x)=sqrt(1+x)-sqrt(1-x)

domain

f (x) = 1 + x - 1 - x

- 1 \leq x \leq 1

Interval Notation

[- 1, 1]

Solution steps

Find non-negative values for radicals:

- 1 \leq x \leq 1

The function domain

- 1 \leq x \leq 1

m = \frac{9}{7}, (2, 5)

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

\frac{1}{2 x - 1}

f (x) = {x^{3} + 1, x \leq 0}

(1, - 5), (- 7, 1)

What is the domain of f(x)=sqrt(1+x)-sqrt(1-x) ?
The domain of f(x)=sqrt(1+x)-sqrt(1-x) is -1<= x<= 1
