Question

The vertex is located at (–3, 5) and the value of a = –5. Write the vertex form of the equation:
a. y = –5(x – 5)^2 – 3
b. y = –5(x – 3)^2 – 5
c. y = 5(x – 5)^2 + 3
d. y = –5(x + 3)^2 +5

Answer 2

\[f (x) = a(x - h)2 + k\]
where (h, k) is the vertex of the parabola

Answer 3

the general form is a(x - b)^2 + c where (b , c) is the coordinates of vertex so put a = -5 , b = = -3 and c = 5
