About This Quiz & Worksheet

Parent functions are an important algebraic concept. Take this interactive quiz to see if you can identify families of functions that go with a given parent function using both graphs and equations.

Quiz & Worksheet Goals

These practice questions will test you on:

  • Families of quadratic, exponential and square root functions
  • What a parent function is
  • Picking out function families using a graph

Skills Practiced

  • Critical thinking - apply what you know about parent functions to graphs of function families and to a problem about square root functions
  • Problem solving - given a particular parent function, solve problems about its function family
  • Defining key concepts - choose characteristics that define the mathematical term 'parent function'

Additional Learning
