domain of f(x)=(sqrt(5-x))-(sqrt(x^2-4))

domain

f (x) = (5 - x) - (x^{2} - 4)

x \leq - 2 or 2 \leq x \leq 5

Solution steps

Find non-negative values for radicals:

x \leq - 2 or 2 \leq x \leq 5

The function domain

x \leq - 2 or 2 \leq x \leq 5

f (x) = 2 x^{2} - 6 x + 10

5 x + 3 y = 12

f (x) = \frac{6 x}{6}

f (x) = \frac{1}{2} x - \frac{9}{2}

2 + 3 + 2 x - x^{2}
