Exponential growth and decay is just a description on how something grows or decays overtime. Example, lets say you have two rabbits and they have babies and their babies have babies and so forth- it wont be long until you have a backyard full of rabbits- can you say Bugs Bunny! This kind of “explosive” growth is called exponential growth in algebra. Likewise a very slow decay like that of radioactive material decaying away is called exponential “decay”. For algebra 1 students you just need to know that exponential functions are different from linear functions. Linear functions can model things that grow in a straight way like time and age. The graphs below are models of exponential functions- you want to remember these..good luck!
