Domain - Linear, Quadratic, and Exponential Models
Cluster - Interpret expressions for functions in terms of the situation they model.
[MI.F-LE.B.5] - Interpret the parameters in a linear function or exponential function (of the form f(x) = bx + k) in terms of a context.*
- Differences between parameters
A difference of numerical characteristics of a population, including measures of center and/or spread. - Exponential function
A function of the form y = a •bx where a > 0 and either 0 < b < 1 or b > 1. The variables do not have to be x and y. For example, A = 3.2 • (1.02)t is an exponential function. - Linear function
A function with an equation of the form y = mx + b, where m and b are constants
[MI.A-SSE.A.1] -
Interpret expressions that represent a quantity in terms of its context.*
[MI.A-SSE.A.1.a] -
Interpret parts of an expression, such as terms, factors, and coefficients.
[MI.A-SSE.A.1.b] -
Interpret complicated expressions by viewing one or more of their parts as a single entity. For example, interpret P(1 + r)n as the product of P and a factor not depending on P.
[MI.F-IF.B.4] -
For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship. Key features include: intercepts; intervals where the function is increasing, decreasing, positive, or negative; relative maximums and minimums; symmetries; and end behavior.*
[MI.F-BF.B.3] -
Identify the effect on the graph of replacing f(x) by f(x) + k, kf(x), f(kx), and f(x + k) for specific values of k (both positive and negative); find the value of k given the graphs. Include linear and exponential models. (Focus on vertical translations for exponential functions). Utilize technology to experiment with cases and illustrate an explanation of the effects on the graph.
[MI.F-LE.A.2] -
Construct linear and exponential functions, including arithmetic and geometric sequences, given a graph, a description of a relationship, or two input-output pairs (including reading these from a table).*
