H (x) = - (x + 11) 2 + 1 what is the vertex

with (-11, 1) as the vertex

Step-by-step explanation:

The vertex form of a parabola is given by

y = a (x-h) ^2 + k

where (h, k) is the vertex

h (x) = - (x + 11) ^2 + 1

is written in vertex form

h (x) = - (x - - 11) ^2 + 1

with (-11, 1) as the vertex
