Question

What is the vertex of the graph of y = -4x(x + 2)^2 + 5

Answer 1

The vertex is the point of coordinates (-2 , 5)

Explanation:

we notice that the equation of the parabola is given in vertex form :

y = -4(x + 2)² + 5

then

y = -4(x − (-2))² + 5

Therefore

The vertex of the graph is the point (-2 , 5)
