domain

f (x) = x + x - 4

x \geq 4

Interval Notation

Solution steps

Find non-negative values for radicals:

x \geq 4

The function domain

x \geq 4

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

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

lo g_{2} (lo g_{3} (lo g_{4} (x)))

f (x) = \frac{12 x ^{2} + x}{x ^{2} + 4}

f (x) = 6 - 3 x

What is the domain of f(x)=x+sqrt(x-4) ?
The domain of f(x)=x+sqrt(x-4) is x>= 4
