1. Melody throws a netball into a net. The path of the netball, from the moment it leaves Melody's hand to the moment it passes through the net, is modelled by the equation

$h(x)=1.8+1.2x-0.2{x}^{2},x\geq0$

where $h$ is the height of the netball above the ground in metres, and $x$ is the horizontal distance travelled by the netball in metres.

Find the height of the netball when it is horizontally halfway between being thrown and reaching its maximum height.
