domain of f(x)=sqrt(1-x^2)-sqrt(x^2-1)

domain

f (x) = 1 - x^{2} - x^{2} - 1

x = - 1 or x = 1

Interval Notation

x = - 1 \cup x = 1

Solution steps

Find non-negative values for radicals:

x = - 1 or x = 1

The function domain

x = - 1 or x = 1

y = - 3 sin (x)

f (x) = \frac{x - 2}{3 x + 7}

f (x) = \frac{( x ^{2} + 4 x + 3 )}{x - 1}

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

f (x) = e^{x}
