Given that `(4,3)` lies on the graph of f(x), find the point that must lie on `-f(2x+10)` :

(1) If x=-8 then y=-f(-6). We don't know what f(-6) is.

(2) If x=18 then y=-f(-26). Again, we do not know the value of f(-26).

(3) If x=-3 then y=-f(4)=-3. Thus the answer is both (2) and (3).

**The solution is (-3,-3)**

** If this is an online class, I suspect an error on the instructor's part. Unfortunately, you will have to guess as to which one will be marked correct. If this is a face to face class, you will be able to point out the error.
