Parabola (U-shaped curve)

$y = ax^2 + bx + c$

Function containing $x^2$ term

Opens upward (minimum turning point)

Opens downward (maximum turning point)

Turning point where parabola changes direction

Vertical line dividing parabola into mirror images

Makes parabola narrower (steeper)

Quadratic function describing real-world situation

$d = \frac{5vt}{18} + \frac{v^2}{170}$
