If the vertex of a parabola is (6,−6)\left(6,-6\right) The Axis of Symmetry uses the ​ h portion of the vertex. Then the range will use the ​​ (a)   part of the vertex's ordered pair. The range of a parabola uses the greater than or equal to ​ ​ (b)   if the vertex is a minimum, and uses the less than or equal to ​ (c)   symbols if the vertex is a maximum. This vertex is a ​ (d)   so the answer would be ​ (e)   .

(y≥k)\left(y\ge k\right)  

(y≤k)\left(y\le k\right)  

k

(y≥−6)\left(y\ge-6\right)  

(y≤6)\left(y\le6\right)
