Requirements

Learn about exponential decay in real-world situations. Problems involve the application of depreciation of an asset and radioactive decay. Learn to apply exponential decay equations and interpret graphs. This is the last of three activities for teaching and learning about exponential functions in algebra: Graphing Exponential Equations; Exponential Growth; and Exponential Decay.

» Lesson Plan and Student Assessment documents are also available.

COMMON CORE STATE STANDARDS FOR MATHEMATICS (2010)

CCSS.MATH.CONTENT.HSF.IF.C.7.E Graph exponential and logarithmic functions, showing intercepts and end behavior, and trigonometric functions, showing period, midline, and amplitude.

CCSS.MATH.CONTENT.HSF.IF.C.8.B Use the properties of exponents to interpret expressions for exponential functions. For example, identify percent rate of change in functions such as y = (1.02)ᵗ, y = (0.97)ᵗ, y = (1.01)12ᵗ, y = (1.2)ᵗ/10, and classify them as representing exponential growth or decay.

CCSS.Math.Content.HSF-BF.B.3 Identify the effect on the graph of replacing f(x) by f(x) + k, k f(x), f(kx), and f(x + k) for specific values of k (both positive and negative); find the value of k given the graphs. Experiment with cases and illustrate an explanation of the effects on the graph using technology. Include recognizing even and odd functions from their graphs and algebraic expressions for them.
