About This Drill

SAT Math: Functions and Function Notation (Drill 1) is a Math practice drill covering Functions and Function Notation. It contains 5 original questions created by Brian Stewart, a Barron's test prep author with over 20 years of tutoring experience.

SAT function questions test your ability to evaluate functions for given inputs, interpret function notation, work with composite functions, determine domain and range, and read function behavior from graphs. This drill covers both algebraic and graphical representations.
