Q:
# Identify the restrictions on the domain of f(x) = quantity x minus 3 over quantity x plus 5. x ≠ 5 x ≠ −5 x ≠ 3 x ≠ −3

Accepted Solution

A:

Answer:x ≠ - 5Step-by-step explanation:Givenf(x) = [tex]\frac{x-3}{x+5}[/tex]The denominator of f(x) cannot be zero as this would make f(x) undefined.Equating the denominator to zero and solving gives the value that x cannot be.solve : x + 5 = 0 ⇒ x = - 5 ← excluded value
