quadratics
factored form
y=a(x+r)(x+s)
r, s: roots / where the parabola crosses the x-axis
a, r, s: constants
to solve x-intercepts:
x-r = 0
x-s = 0
vertex form
y=a(x-h)^2+k
a, h, k: constants
(h,k): vertex of the parabola
standard form
ax^2+bx+c
a, b, c: constants
c: y-intercept / where the parabola crosses the y-axis
parabola
U-shaped curve drawn for a quadratic function
+a: parabola opens up
-a: parabola opens down
axis of symmetry
a vertical line that divides the parabola into two congruent halves
always passes through the vertex of the parabola
