Answer:
The vertex will be found at (-5, -28)
Step-by-step explanation:
Vertex form uses the following formula:
y = a(x-h)^2 + k
Identify the values of h and k in your function:
(x+5)^2 - 28
h = -5, k = -28
The vertex is found with the following point:
(h,k)
Vertex: (-5, -28)
The vertex will be found at (-5, -28)
Answer:
6 books for $21
Step-by-step explanation:
