domain of f(x)= 2/(sqrt(x+5))

domain

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

x > - 5

Interval Notation

(- 5, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - 5

Find undefined (singularity) points:

x = - 5

Combine real regions and undefined points for final function domain

x > - 5

y = 8 x + 7

f (x) = 4 \cdot x^{2} - 3 \cdot x - 12

f (x) = 3 x^{3} - 18 x^{2} + 100

2 x + 3 y = 18

f (x) = 3 x^{4} - 30 x^{2} + 27

What is the domain of f(x)= 2/(sqrt(x+5)) ?
The domain of f(x)= 2/(sqrt(x+5)) is x>-5
