domain of f(x)=sqrt(-x)+5

domain

f (x) = - x + 5

x \leq 0

Interval Notation

(- \infty, 0]

Solution steps

Find non-negative values for radicals:

x \leq 0

The function domain

x \leq 0

f (x) = \frac{1}{2} x - 15

f (x) = - 5 x - 3

(- 2.8) (7)

f (x) = \frac{x ^{2} - 3 x - 18}{x - 8}

\frac{( e ^{x} )}{8 + e ^{x}}
