What is the axis of symmetry of h(x) = –2x2 + 12x – 3?

Characteristic of the axis of symmetry:

* It is the line of symmetry of a parabola that divides a parabola into two equal halves that are reflections of each other about the line of symmetry.

* It intersects a parabola at its vertex.

* It is a vertical line with the equation of

Given the quadratic equation:

Compare above equation with general quadratic equation to find the values of a and b;

then the value of a= -2 and b = 12

Then, the axis of symmetry is given by:         ......[1]

Substitute the value of a and b in  [1],

therefore, the axis of symmetry of is, x = 3

300pi

step-by-step explanation:

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
