If f(-9) = -11, then f( f^-1( -11))=

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3
