Hard expontential question I don't understand

So...

t₀ = 2
t₂ = 3.81
t∞ = 12

h = A - Be^-kt
2 = A - B
3.81 = A - Be^-2k
12 = A - Be^-k∞

...How do I proceed this question?

Thanks..

The first thing you notice is that A is 12 I believe as when t = infinity

\frac{B}{e^kt}

becomes closer and closer to zero and as the maximum height is 12 then A has to equal 12
