domain of f(x)= 2/(sqrt(x))

domain

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

x > 0

Interval Notation

(0, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 0

Find undefined (singularity) points:

x = 0

Combine real regions and undefined points for final function domain

x > 0

y = - 2 x + 5

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

8 x + 9 y = 18

y = \frac{3 x}{x + 2}
