**Function basics and Quadratics**

A mixture of calculator and non-calculator skills linking functions with graphs.

**Syllabus content**: SL 2.2, SL 2.5, SL 2.6, SL 2.7

I have made 5 worksheets and 4 treasure hunts to help with this topic. They are:

- Basic functions
- Quadratics
- Solutions of quadratics
- Angry bird quadratics
- Bridge building
- Treasure hunt: discriminant of quadratics
- Treasure hunt: functions domains and ranges
- Treasure hunt: graphing skills
- Treasure hunt: quadratic basics

You can scroll down below to see the images of the questions. You can download both the questions and mark scheme from the bottom of the page.

**1. Basic functions**

Note: This is a short worksheet which can be used in lesson or for homework. It covers syllabus point: SL 2.2 and SL 2.5. Students explore domains and ranges and function notation as well as inverses.

**2. Quadratics**

Note: This is a short worksheet which can be used in lesson or for homework. It covers syllabus point: SL 2.6. Students work with quadratic equations and sketch graphs.

**3. Solutions of quadratics**

Note: This is a short worksheet which can be used in lesson or for homework. It covers syllabus point: SL 2.7. Students work with the discriminant of quadratics to find the number of solutions.

**4. Angry Bird quadratics**

Note: This is an investigation idea which starts by tracking data from a video, and then uses regression on Desmos to model projectile motion.

**5. Bridge Building:**

Note: This is an investigation idea which looks at the shapes of bridges and how closely they follow a quadratic curve.

**Treasure hunt: Discriminant of Quadratics**

Note: This is an activity which can be done in pairs or as a whole class activity. Students solve a mixture of discriminant problems.

**Treasure hunt: Functions Domains and Ranges**

Note: This is an activity which can be done in pairs or as a whole class activity. Students solve a mixture of problems around domain and range.

**Treasure hunt: graphing skills**

Note: This is an activity which can be done in pairs or as a whole class activity. Students solve a mixture of graph sketching problems.

**Treasure hunt: quadratic basics**

Note: This is an activity which can be done in pairs or as a whole class activity. Students solve a mixture of quadratic problems.
