What is the vertex of the graph of y = −1(x − 2)2 + 3?
(3,-2)
(-2,3)
(3,2)
(2,3)
2 answers:
The vertex form is y=a(x-h)²+k
the vertex is (h,k)
so
y=-1(x-2)²+3
compare to
y=a(x-h)²+k
2=h and 3=k
the vertex is (2,3)
4th option
Answer:
(2,3)
Step-by-step explanation:
An equation of the form
can be expressed in the Vertex Form:
where the vertex is always:
(h, k)
The vertex is the lowest or highest point of the parabola.
When we compare the two functions:
We can see that
a = -1
h = 2
k = 3
So the vertex is:
(h, k) = (2, 3)
I hope this helps!

Step-by-step explanation:
4c+3=15
You need to get rid of the 3
So you minus it from each side so you
4c=12
12/4=3
So c =3
It is 838
