Unit 6 - Quadratics

Question 1

Y = ax^2 + bx + c

Form?

Order?

Answer 1

Standard Form

1. Y intercept: at x = 0
2. X intercept: at y = 0
3. Vertex : need to find midpoint of x coordinates and sub in for y coordinate

Question 2

Y = a (x - a) (x - b)

Form?

Order?

Answer 2

Factored Form

1. X intercepts using null factor law
2. Y intercept: at x = 0
3. Vertex: need to find midpoint of x coordinates and sub in for y coordinate

Question 3

y = a (x - h) ^2 + k
Form?

Order?

Answer 3

Vertex form

1. Vertex @ (-h,k)
2. Y intercept: at x = 0
3. X intercepts: y = 0 & solve using inverse operations
