Queremos plantar 147 árboles en un terreno de forma cuadrada ¿cuantas filas de árboles habrá? ¿sobraran árboles?

The co-ordinates of the vertex of the function y-9= -6(x-1)^2 is (1, 9)

Solution:

Given, equation is

We have to find the vertex of the given equation.

When we observe the equation, it is a parabolic equation,

We know that, general form of a parabolic equation is  

Where, h and k are x, y co ordinates of the vertex of the parabola.

By comparing the above equation with general form of the parabola, we can conclude that,

a = -6, h = 1 and k = 9

Hence, the vertex of the parabola is (1, 9).
