domain of f(x)=sqrt(x^2-144)

domain

f (x) = x^{2} - 144

x \leq - 12 or x \geq 12

Solution steps

Find non-negative values for radicals:

x \leq - 12 or x \geq 12

The function domain

x \leq - 12 or x \geq 12

f (x) = \frac{3 x ^{2} + 4}{5}

f (x) = \frac{8}{- x ^{2} - 5 x + 14}

f (x) = \frac{8 x}{x - 2}

f (x) = x^{2} - 6 x + 5

f (x) = 2 sin (\frac{1}{2} x)

What is the domain of f(x)=sqrt(x^2-144) ?
The domain of f(x)=sqrt(x^2-144) is x<=-12\lor x>= 12
