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
See attached picture
The answer is 3n because the 3 is the coefficient
118.56. 31.2 x 3.8 = 118.56
C=2•pi• R
D=6 then the radius is 3
2•Pi•3 =18.85
4/3 • 5/3 = 20/9 divided by 2 = 10/9
