Also, Is the formula for radioactive decay the same as the formula for exponential growth?
Thank you

Decay, , showing the as a subscript;
The negative sign in the exponent is to help show that your equation is meant for decay, and this assumes .
-
Use the equation, or the format for either exponential decay or for radioactive decay, or any exponential continuous decay.
Exponential Growth, .
You may choose to say as the function name, for A being a function of t.
The half-life (for exponential decay) can be easily found picking and and then solving for t. Usually you have some data for t and A and when you look for a value, because you may also want to find k.
