What is the difference between an oxygen molecule and an ozone molecule

I remember doing this last year. Domain (-2, %) goes in the third image , domain { -1, -2 and so on) goes in the second image , domain {-1,0,1,5) goes in the first image , the third and second image are not functions , the first image is a function , range (%, %) goes in the third image , range (-4,0 and so on) goes in the second image and the last thing which is the range (3,5,7) goes in the first image
