Grade 8. This describes the skill, not a learner estimate.
Comparing functions
Compare function behavior across tables graphs and equations
Problem types
- Select the tables with a smaller or larger intercept
- Compare two functions
- Linear or not linear
Builds on
- What makes a relation a function
- Slope of a line
- Comparing fractions with benchmarks · Useful idea
Comparing rates of change of two functions compares the fractions that give their slopes.
Leads to
- Linear models of a situation
- Comparing functions given in different forms
- Linear growth against exponential growth · Extend the idea
Comparing rates of change of two functions extends to comparing linear and exponential growth over long times.
