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 :)
