Tofer's Lecture on Exponential Decay
![](../../_Media/placeholder_med.jpeg)
What you need to be able to do after this class: (1) sketch exponential decay functions using translations and intercepts (f(x) = a*b^-(x-h)+k; (3) evaluate an exponential function for a given value; (4) apply formulas for radioactive decay and half-life.
Necessary Vocabulary: base, exponent, exponential decay, asymptote, translation, end behavior, half-life, radioactive decay, negative exponents.
