F.LE.2: Constructing Linear and Exponential Functions from Graphs, Descriptions, and Input-Output Pairs

Grade: Functions

Domain: LE: Linear, Quadratic, and Exponential Models

Standard Description

Construct linear and exponential functions, including arithmetic and geometric sequences, given a graph, a description of a relationship, or two input-output pairs (include reading these from a table).

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.
