F.LE.1c: Understanding Constant Percent Rate Growth and Decay

Grade: Functions

Domain: LE: Linear, Quadratic, and Exponential Models

Standard Description

Recognize situations in which a quantity grows or decays by a constant percent rate per unit interval relative to another.

Domain Description

Understand that linear functions increase by consistent differences over identical intervals, while exponential functions rise by reliable factors during equal intervals. Detect circumstances where one variable alters at a consistent rate per unit interval corresponding to another. Identify cases where a variable enhances or diminishes by a continuous percentage rate per unit interval related to another. Create linear and exponential functions, even arithmetic and geometric sequences, from a graph, a relationship description, or two input-output pairs. Utilize graphs and tables to identify that a quantity, when rising exponentially, surpasses an increasing quantity linearly, quadratically, or as a polynomial function. For exponential models, solve abct = d as a logarithm where a, c, and d are numbers while the base b is 2, 10, or e; use technology to evaluate the logarithm. Lastly, translate the parameters in a linear or exponential function in terms of a context.
