domain of f(x)=sqrt(x^2-4)-sqrt(4x-x^2)

domain

f (x) = x^{2} - 4 - 4 x - x^{2}

2 \leq x \leq 4

Interval Notation

[2, 4]

Solution steps

Find non-negative values for radicals:

2 \leq x \leq 4

The function domain

2 \leq x \leq 4

f (x) = 9 x

h (x) = 27 - 9 x

ln (t + 2)

f (x) = \frac{2}{9 + e ^{x}}

f (x) = \frac{1}{2 - 10 x + 25}

What is the domain of f(x)=sqrt(x^2-4)-sqrt(4x-x^2) ?
The domain of f(x)=sqrt(x^2-4)-sqrt(4x-x^2) is 2<= x<= 4
