What is the line that cuts a graph of a quadratic function in half?

Axis of symmetry

Step-by-step explanation:

The maximum or minimum point on the parabola is the vertex

To cut the parabola into two congruent halves, we use vertex

A vertical line that crosses the vertex cuts the parabola in two halves.

The vertical line that crosses the vertex is called as axis of symmetry.

So, the axis of symmetry  is the line that cuts a graph of a quadratic function in half.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
