New cards

Transforming Quadratics (Vertex Form)

(x-h)² + k (h = x-int) (k= y-int)

2
New cards

Standard Form

Ax²+Bx+C (C = y-intercept of the quadratic function)

3
New cards

Intercept Form (FACTORED FORM)

a(x-p)(x-q) (p and q = x-ints) (p,0) & (q,0)

4
New cards

Quadratic Formula

-b ± √b² - 4(a)(c) / 2(a) is used to find the roots of a quadratic equation in the form Ax² + Bx + C = 0. (Gives x-int and axis of symmetry)

5
New cards

X value and Axis of symmetry

-b/2(a)

6
New cards
