Question

What are the coordinates of the vertex of the function below? Write your

answer in the form (x,y).
y-11=-(x-5)^2

Answer 1

(5, 11 )

Explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Given

y - 11 = - (x - 5) ← add 11 to both sides

y = - (x - 5)² + 11 ← in vertex form

with vertex = (5, 11 )
