The axis of symmetry of the graph of y = -(x+4)2 -6 is

= 6
x = -4
x = -6
x = 4

x=-4

Step-by-step explanation:

The axis of symmetry is a vertical line through the vertex with. It is written as x = h where h is the x-coordinate of the vertex.

Here the vertex is (-4,-6). So the axis of symmetry is x = -4

answer

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a

21
