Answer:
C.(-5, 4)
Step-by-step explanation:
The vertex form of a parabola of this type is:
y = a ( x − h ) 2 + k [1]
where ( h , k ) is the vertex.
Explanation:
Given:
y = 7 ( x + 5 )² + 4 [2]
We can convert equation [2] into the same form as equation [1] by writing
+5 as − − 5 :
y = 7 ( x − − 5) ² + 4 [3]
We observe that the vertex is
( − 5 , 4 )
hope it will help :)
