1 and 2




0.5 and 3.5




1.8 and 2.15




1 and 2.5

Answer 1

Your answers are wrong.

Answer 2

f(x)=[[x-3.2]]-1 /2

This is f(x)-4.2, then divided by 2.

f(8.5) is in one of your answer choices

8.5-4.2=4.3/2=2.15

however (5.8) is not..

Answer 3

check for typos..

Answer 4

okay thanks

Answer 5
