Linear and Exponential Models
High School
Score 4.0
In addition to score 3.0 performance, the student demonstrates in-depth inferences and applications that go beyond what was taught.
Score 3.5
Score 3.0
In addition to score 3.0 performance, partial success at score 4.0 content
The student will:
• 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) (HSF-LE.A.2)
• Observe using graphs and tables that a quantity increasing exponentially eventually exceeds a quantity increasing linearly, quadratically, or as a polynomial function (HSFLE.A.3)
• 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 using technology (HSF-LE.A.4)
Score 2.5
Score 2.0
No major errors or omissions regarding score 2.0 content, and partial success at score 3.0 content
The student will recognize or recall specific vocabulary, such as:
• Arithmetic, base, constant, construct, decay, difference, equal, evaluate, exceed, exponential, exponential function, express, factor, geometric, graph, grow, increase, inputoutput pair, interval, linear, linear function, logarithm, model, number, percent, polynomial function, prove, quadratic, quantity, rate, relationship, relative, sequence, solution,
table, technology, unit
The student will perform basic processes, such as:
• Distinguish between situations that can be modeled with linear functions and with exponential functions (HSF-LE.A.1)
• Prove that linear functions grow by equal differences over equal intervals and that exponential functions grow by equal factors over equal intervals (HSF-LE.A.1a)
• Recognize situations in which one quantity changes at a constant rate per unit interval relative to another (HSF-LE.A.1b)
• Recognize situations in which a quantity grows or decays by a constant percent rate per unit interval relative to another (HSF-LE.A.1c)
