What are the coordinates of the vertex of the parabola described by the equation below? y = -7(x - 4)2 - 5

Ladonna · Answer

Answer:   V ( 4,-5)   Step-by-step explanation:   -7( X -4 )²= y+5  ( X - 4)² = -1/7 (y+5)  Compare with ( X - h)² = -4p ( y-k)  Therefore, h = 4, k = -5  Vertex, V = (h,k)  V (4,-5).
