Linear, Quadratic, and Exponential Models

Resources

Construct and compare linear, quadratic, and exponential models and solve problems. [Linear and exponential]
1. Distinguish between situations that can be modeled with linear functions and with exponential functions. tools-icon
a. Prove that linear functions grow by equal differences over equal intervals, and that exponential functions grow by equal
factors over equal intervals.
b. Recognize situations in which one quantity changes at a constant rate per unit interval relative to another.
c. Recognize situations in which a quantity grows or decays by a constant percent rate per unit interval relative to another.
2. 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).

3. Observe using graphs and tables that a quantity increasing exponentially eventually exceeds a quantity increasing linearly,
quadratically, or (more generally) as a polynomial function.
tools-icon
Interpret expressions for functions in terms of the situation they model.
5. Interpret the parameters in a linear or exponential function in terms of a context.
