Question

Give the domain of each of the following functions in interval notation.
f(x)=$\sqrt[3]{-10x+3}$
h(x)=$\sqrt[8]{-2x-10}$

Answer 1

Answer:

the domain of f(x) is R  ⇒ ] -∞ , ∞[

the domain of h(x) is x ≤ -5 ⇒ ] -∞ , -5]

Step-by-step explanation:

h(x) = \sqrt[8]{-2x-10}

-2x - 10 ≥ 0

-2x ≥ 10

x ≤ -5
