Question

Identify the vertex of the graph

Answer 1

Answer:

(-1,-3)

Step-by-step explanation:

Answer 2

Answer:

y = a(x – h)2 + k,

Step-by-step explanation:

Parabolas always have a lowest point (or a highest point, if the parabola is upside-down). This point, where the parabola changes direction, is called the "vertex". If the quadratic is written in the form y = a(x – h)2 + k, then the vertex is the point (h, k). This makes sense, if you think about it.
