What's the vertex and axis of symmetry of y= -2x^2 + 8x-20

Vertex

V  = (2, -12)

Axis of symmetry

x = 2

Step-by-step explanation:

To answer this question suppose the general equation of a parabola of the form:

Where a, b and c are constants that belong to real numbers.

So it is known that the vertex of this parable is:

So, we use this same formula to find the vertex of the parabola

Where:

The vertex of the parabola is at the point

V = (2, -12)

Finally, the axis of symmetry of a parabola always passes through its vertex. Then the axis of symmetry is the straight line

x = 2

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
