Y  = - x^2 - 2

the vertex of - x^2 will be at (0,0)
the -2 translates the graph down 2 units

The answer is the vertex is at (0,-2)  and  as the coefficient of x^2 is negative it is a maximum

Answer is  D.

Answer:

(0, –2); maximum

Step-by-step explanation:

y = -x^2 - 2

WE are given with the quadratic equation.

Vertex form of quadratic equation is in the form of y=a(x-h)^2+k

where (h,k) is the vertex

y = -(x-0)^2 - 2

The value of a=-1

when the value of 'a' is negative, then the vertex is maximum

To find the vertex we look at the value of h  and k

h=0 and k= -2

Vertex is (0,-2)

(0, –2); maximum

Answer:

A. (x - 3)(x + 3)

Step-by-step explanation:

From the graph the x-axis is crossed by the graph at different points which are;

x = 3  and x = -3

This means the solutions are : x = 3 and x =-3

The factors will form the following equation : (x - 3)(x + 3)
