To find this derivative, we will need to use the chain rule.
As there is a variable in the exponent we can use this formula:
In this case, and
This means that and respectively
This gives us
note : (e^(u(x))' = (u(x))'e^(u(x)
f(x)= e^(4x) + e^-(4x)
f'(x) =4e^(4x) - 4 e^-(4x)
chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.
