Answer:
Step-by-step explanation:
f(x) = 6(x+2)²-6
f⁻¹(f(x)) = x
f(x) = t => 6(x+2)²-6 = t =>
=> 6(x+2)² = t+6 =>
=> (x+2)² = t/6 + 1
=> x+2 = ±√(t/6 + 1)
=> x = ±√(t/6 + 1) - 2
=> f⁻¹(x) =
{√(x/6 + 1) - 2, x > -6
{-√(x/6 + 1) - 2, x ≤ -6
10 teams (1 remainder)
if each team has 3 players and there are 30 friends, divide that and youll end up with 10 teams. you will also have 1 remaining player
