Equations of Parabolas (HSC SSCE Mathematics Advanced): Flashcards

$f(x) = ax^2 + bx + c$

$f(x) = a(x - h)^2 + k$

$f(x) = a(x - x_1)(x - x_2)$

y-intercept

The vertex

x-intercepts (roots or zeros)

Concave up (opens upward)

All real numbers ($\mathbb{R}$)

Vertex and one other point

x-intercepts and one other point
