CCSS.Math.Content.HSF-IF: : Interpreting Functions
CCSS.Math.Content.HSF-IF.A: : Understand the concept of a function and use function notation
CCSS.Math.Content.HSF-IF.A.1: : Understand that a function from one set (called the domain) to another set (called the range) assigns to each element of the domain exactly one element of the range. If f is a function and x is an element of its domain, then f(x) denotes the output of f corresponding to the input x. The graph of f is the graph of the equation y = f(x).

About STEM Cases
Students assume the role of a scientist trying to solve a real world problem. They use scientific practices to collect and analyze data, and form and test a hypothesis as they solve the problems.
![Realtime reporting icon](/Assets/img/blank.gif)
Each STEM Case uses realtime reporting to show live student results.
Introduction to the Heatmap
![Time icon](/Assets/img/blank.gif)
