How to Find the Vertex FAST — Using Desmos

Boost SAT Math Scores in Minutes With This Desmos Trick

If your child is prepping for the SAT, here’s a quick tip that could raise their score—and cut their stress—in minutes.

🎯 Learn to find the vertex of a parabola using Desmos.

It’s simple, it’s fast, and it’s something every Sharpe Sessions SAT tutor teaches. Why? Because this one skill shows up repeatedly on the test—and mastering it can save valuable time (and points).

Here’s How It Works:

Instead of struggling through standard-form equations like
y = ax² + bx + c,
students can plug the equation into Desmos, and:

✔ Quickly visualize the graph
✔ Identify the vertex instantly
✔ Double-check their work without second-guessing

Why This Matters for the SAT

SAT math is as much about strategy as it is about content. When students use Desmos smartly, they can:

✅ Avoid costly algebra errors
✅ Eliminate wrong answer choices with confidence
✅ Solve problems faster—giving them more time for tougher questions

Our math tutors and SAT tutors in Atlanta, Conyers, and Jamaica coach students on how to use Desmos like a pro. Inside the SAT Ivy Surge Program, we teach specific graphing shortcuts, time-saving strategies, and test-day confidence techniques.
