g(x)=2x-4+3

g(x)=2x- 1

2, left plus right minus f(x-2)=√3-(x-2)

f(x-2)=√5-x？ What about the new features? f(x)=√5-x？

3. The picture has been inserted. Will odd function be symmetrical about the origin? The minimum value of f(x) in the interval [a, b] is f(a)=m, so the corresponding value of f(-a) in [-b, -a] should be the maximum value -m,? You can tell by looking at the picture that it is in [-b, -a]? There are more and more functions.
