Discover how straight lines and curves behave differently in mathematics
Create straight lines that never curve
• Same change every step
• Constant slope everywhere
• Graph is always straight
Form U-shaped curves called parabolas
• Rate of change varies
• Has a turning point
• Creates symmetric curves
Click a preset to see the difference:
1. As a Machine: Put in x, get out y. Linear functions add/multiply by fixed amounts. Quadratic functions square the input.
2. As a Pattern: Linear patterns grow steadily. Quadratic patterns accelerate - they grow slowly then quickly (or vice versa).

Match your function to the mystery graph!
Can you recreate this function? Adjust the sliders below to match the green graph!
Start with y = x and transform it to match:
Let's figure this out together! I'll look at the graph and see what patterns I notice. Try adjusting the sliders and see how close you can get!
