domain of f(x)=sqrt(-20-x)

domain

f (x) = - 20 - x

x \leq - 20

Interval Notation

(- \infty, - 20]

Solution steps

Find non-negative values for radicals:

x \leq - 20

The function domain

x \leq - 20

- 2 x^{2} + 5

(- 8.7) (- 9.11)

g (x) = 6 x + 18

f (x) = 2 + x - 6

x^{4} + \frac{4}{3} x^{3} - 4 x^{2} - \frac{4}{3}
