Algebra and functions
Practice equations, expressions, functions, systems, and modeling. Review both the setup and the algebraic steps when a question goes wrong.
Geometry and data
Work on geometry, measurement, statistics, probability, and data interpretation. Pay attention to units, diagrams, and what the question actually asks you to calculate.
Build a repeatable process
Use untimed practice to build accuracy, then introduce timed sets after your solution process is consistent.
By the Numbers
The ACT Math question bank on this site includes 120 original questions, covering number and quantity, algebra, functions, geometry, statistics, and probability.
Worked Example
Question: If f(x) = 2x² − 3x + 1, what is f(−2)?
- A) 3
- B) 9
- C) 15
- D) 23
Show answer and explanation
Correct answer: C) 15. Substitute x = −2: 2(−2)² − 3(−2) + 1 = 2(4) + 6 + 1 = 8 + 6 + 1 = 15.
