domain of f(x)= 2/(sqrt(x+3))

domain

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

x > - 3

Interval Notation

(- 3, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - 3

Find undefined (singularity) points:

x = - 3

Combine real regions and undefined points for final function domain

x > - 3

f (x) = \frac{5 x + 4}{7}

(2.2) (- 3.7)

y = - 2 x^{2} + x

f (x) = \frac{6 x}{7 - x}
