Verify if these are correct answers.
1. The derivative of f(x)=e^2x -e^-2x
is f'(x)=2e^2x - 2e^-2x?
2.A certain radioactive substance is decaying so that at time t, measured in years, the amount of the substance, in grams, given by the function f(x)=3e^-3t. What is the rate of decay of the substance after half a year?
Yes for both. Growth and decay problems are awful, just letting you know
