Where a Function Increases, Decreases, or Stays Constant: Sample FAST Questions

Reading a graph for behavior is an 8th grade function skill: finding the stretches where the graph rises, falls, or runs flat. Students describe a graph in words and also sketch a graph that matches a written description.

How the FAST tests this benchmark

FAST items include multiple choice questions naming where a function increases or decreases, graphic response items sketching a described graph, and matching items pairing stories with graphs. Functions stay continuous here, so there are no jumps or gaps to interpret.

Skills students need

  • Identify intervals where a function is increasing
  • Identify intervals where a function is decreasing
  • Identify intervals where a function is constant
  • Sketch a graph from a written description
