Describe an exponential function and the exponential decay equation.

An exponential function increases slowly at first and then very rapidly. In the case of decay it would decrease very rapidly and then slow down. It never incepts with the x-axis and only once with the y-axis. N(t)=N(0)exp(-lamdat)N(t)...Number of particles at time t N(0)...Initial Number of particles; Number of particles at time = 0-lambda...decay constant t...time
