Functions: Domains and Graphs

• Example 1: Find the Domain of f(x) = 1 / √(5+x)
• Example 2: Find the domain of h(x) = √(8-2x) / (6-3x)

<aside> Notation Reference:

• x ∈ (-∞, 2) means x is in the interval from negative infinity to 2, excluding 2
• (2, 4] means the interval from 2 to 4, excluding 2 but including 4
• Parentheses ( ) indicate excluded endpoints
• Brackets [ ] indicate included endpoints
• ⇔ means "equivalent to" or "if and only if" </aside>
