Answer:
D
Explanation:
Given
f(x) =
← cancel (x + 2) on the numerator/ denominator
This creates a discontinuity ( a hole ) at x = - 2
f(x) =
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.
x - 3 = 0 ⇒ x = 3 ← excluded value
Thus domain is x → D
