    Please find the value

    The symbol [x] means the greatest interger not greater than x.
    If f(x)=[2x]-3x, find each value.
    f(0)=2*0-3*0=0
    f(0.5)= 2*0.5-3*0.5=1-1.5=-0.5
    f(-3.5)=-7+10.5=3.5
    f(x-1)=1-x

    I just plugged in numbers instead of x. Is it correct or not?
    Thank you very much.
