Hello, oceanmd!
You are correct . . . good work!
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.
