Quadratic Functions (Grade 10 NSC Matric Mathematics): Flashcards

$y = ax^2 + q$ where $a$ and $q$ are constants

Parabolas (U-shaped or inverted U-shaped curves)

Vertical shift: up if $q > 0$, down if $q < 0$

Opens upward (smile) with minimum turning point

Opens downward (frown) with maximum turning point

$(0, q)$

$(0, q)$

All real numbers ($\{x : x \in \mathbb{R}\}$)

$[q; \infty)$

$x = 0$ (the y-axis)
