## Standards in this domain:

### Construct and compare linear, quadratic, and exponential models and solve problems.

• F-LE.1.Distinguish between situations that can be modeled with linear functions and with exponential functions.
• Prove that linear functions grow by equal differences over equal intervals, and that exponential functions grow by equal factors over equal intervals.
• Recognize situations in which one quantity changes at a constant rate per unit interval relative to another.
• Recognize situations in which a quantity grows or decays by a constant percent rate per unit interval relative to another.
• F-LE.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).
• F-LE.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.
• F-LE.4. For exponential models, express as a logarithm the solution to abct = d where a, c, and d are numbers and the base b is 2, 10, or e; evaluate the logarithm using technology.

### Interpret expressions for functions in terms of the situation they model.

• F-LE.5. Interpret the parameters in a linear or exponential function in terms of a context.
