Graph the quadratic functions y= -2x^2 and y= -2x^2 + 4 on a separate piece of paper. using those graphs compare and contrast the shape and position of the graphs.

Step-by-step explanation:

Both are parabolas open down.

The first one has vertex as (0,0) but second parabola has vertex as (0,4)

The second parabola is nothing but a transformation of the first parabola by a shift of 4 units verticaly up.

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.
