Which equation has a graph that is a parabola with a vertex at (–2, 0)?
2 answers:
Answer:
The vertex of a quadratic equation corresponds to the point where the maximum or minimum value is located.
If the function has a positive leading coefficient, the vertex corresponds to the minimum value.
If it has a negative leading coefficient, the vertex corresponds to the maximum valuevalue
If the vertex is located at
(–2, 0)
The possibilities are
y = (x-2)^2
or,
y = - (x-2)^2
Since the problem tells us the answer, we adopt the positive values
Answer:
y = (x-2)^2

Answer:

Step-by-step explanation:
A graph that is a parabola with a vertex at (–2, 0)
Vertex form of parabola equation is

where (h,k) is the vertex
WE are given with vertex (-2,0)
(-2,0) is (h,k)
h=-2 and k=0
Plug the value in vertex form of equation. Lets take a=1

Equation becomes
