Identify a function
- 8.F.2 - Compare properties of 2 functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions)
Equation & table
Equation & Verbal description
Distance-time graphs & distance-time equations
Use functions to model relationships between quantities.
- 8.F.4 - Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph. Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values.
- 8.F.5 - Describe qualitatively the functional relationship between two quantities by analyzing a graph (e.g., where the function is increasing or decreasing, linear or nonlinear). Sketch a graph that exhibits the qualitative features of a function that has been described verbally.
