Study Guide — HSF.LE.A.2
Construct linear and exponential functions, including arithmetic and…
Compare linear, exponential, and quadratic models; fit data when appropriate.
What this standard means
- 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).
- Apply construct linear and exponential functions, including arithmetic and… with models and explanation
- Identifies appropriate model type

How to use the 20 practice sets
| Sets | When to use | | --- | --- | | 1–5 | Intro — explore together, short written items | | 6–10 | Core skills — diagrams and written practice | | 11–15 | Mixed review — explain thinking | | 16–20 | Stretch — word problems and mastery tasks |
Pacing: 10–15 minutes per session.
How to practice
1. Look at differences or ratios in tables 2. Choose model based on growth pattern 3. Interpret parameters in context

Common mistakes
- Using linear model for exponential data
- Ignoring domain restrictions
Review and practice tests
1. Start Review 1/10 when sets 1–3 feel comfortable. 2. Move up one review level with little help. 3. Use Practice Test 4/10–6/10 for mid-standard checks. 4. Practice Test 10/10 is the mastery bar for HSF.LE.A.2.
- [ ] Identifies appropriate model type
