Parabolas - Double the distance from the `x` axis

`y=2x^2` - Double the distance from `x`  axis.

 To prove this, plot the graph.

Try different values of `x`

`x=3`   `y=2times3^2` `=2times9` `=18`
`x=2`   `y=2times2^2` `=2times4` `=8`
`x=1`   `y=2times1^2` `=2times1` `=2`
`x=0`   `y=2times0^2` `=2times0` `=0`
`x=-1`   `y=2times(-1)^2` `=2times1` `=2`
`x=-2`   `y=2times(-2)^2` `=2times4` `=8`
`x=-3`   `y=2times(-3)^2` `=2times9` `=18`

 

To enlarge a parabola you need to double the distance from the x axis

 Notice the parabola is double the distance from the `x`  axis.

Notice the doubled distance of the example on the graph
