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

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60
