x \geq 0

Interval Notation

Solution steps

Find non-negative values for radicals:

x \geq 0

The function domain

x \geq 0

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

x^{2} - 2 x - 3

\frac{1}{9} sin (7 x + \frac{π}{2})

\frac{2 x + 3}{5 x + 4}

y = x - 4

What is the domain of f(x)=sqrt(5x)+4x-9 ?
The domain of f(x)=sqrt(5x)+4x-9 is x>= 0
