Question

How to find the vertex, axis of symmetry, min or max value of a quadratic function

Answer 1

I just need to be able to identify all that from an equation but idk how

Answer 2

I know there's standard form: Ax^2 + Bx + C
Vertex form: a(x - h)^2 + k
Intercept: a(x-R1)(x-R2)

Answer 5

When given the Vertex Form,
(h,k) is the vertex
x = h is the axis of symmetry
y = k is the min or max

The min or max of a quadratic depends on the value of a

If a > 0, then y = k is the min
If a < 0, then y = k is the max
