domain of f(x)=sqrt(-x-13)

domain

f (x) = - x - 13

x \leq - 13

Interval Notation

(- \infty, - 13]

Solution steps

Find non-negative values for radicals:

x \leq - 13

The function domain

x \leq - 13

- 3 sin (\frac{π}{2} x) + 1

- x^{2} + 5 x + 1

f (x) = x^{2} - 5 x + 4

\frac{x ^{3}}{x + 1}

(- 7, 2), (3, - 3)
