### GRE Quantitative Reasoning Objectives

The GRE is intended to assess your preparedness for undertaking graduate study. About a third of the exam is dedicated to quantitative reasoning questions. Our functions tutorials offer instruction in areas that appear on the quantitative portion of the test. Particular topics that these lessons cover include:

• Understanding and using function notation
• Determining a function's domain and range
• Formulating and interpreting compositions of functions
• Performing arithmetical actions (multiplication, subtraction, etc.) on functions
• Indicating functions on a graph
• Understanding composite functions
• Working with inverse functions
