WebExponential decay refers to a process in which a quantity decreases over time, with the rate of decrease becoming proportionally smaller as the quantity gets smaller. Use the exponential decay formula to calculate k, calculating the mass of carbon-14 remaining after a given time, and calculating the time it takes to have a specific mass remaining. WebSo the standard form for a quadratic is y=a(b)^x. So one basic parent function is y=2^x (a=1 and b=2). Learning the behavior of the parent functions help determine the how to read the graphs of related functions. You start with no shifts in x or y, so the parent funtion y=2^x has a asymptote at y=0, it goes through the points (0,1) (1,2)(2,4)(3 ...
