You are supposed to pick the appropriate branch of the function depending on the value of x asked for, and evaluate the function.

a) f(7)
You use the function branch correpsonding to .

b) f(4)
Use the branch corresponding to .

c) f(-3)
Obviously, this is for , so pick the corresponding function branch.
