Answer
A
open paren 12 comma negative 18 close paren
B
open paren 0 comma 1 close paren
C
open paren 9 comma negative 15 close paren
D
open paren 6 comma 3 close paren
Explanation
A point (x, h(x)) on h becomes (h(x), x) on the inverse. Since h(3) = 6, the point (3, 6) on h gives the point (6, 3) on h⁻¹. So the correct choice is (6, 3).
