Functions whose graphs resemble sets of stairsteps are known as step functions. The most famous of the step functions is the greatest integer function, which is denoted by:

$f(x)=[x]$

which graph is shown in the Figure below. As you can see from the graph:

$if \ x=-1.8 \ then \ f(-1.8)=[-1.8]=-2$

Therefore:

$f(-1.8)=-2[-1.8]+8=-2(-2)+8=\boxed{12}$

So the right answer is 12
