<span>ralph = r
sara = s
ralph is TODAY, 3 times older, so if sara is "s" old, ralph is 3s
r = 3s
in 6 years, ralph will be 2 times as old as sara THEN,
in 6 years ralph will be TODAY's age plus 6, so r + 6
so if sara is "s" old, r+ 6 = 2s
r + 6 = 2s</span>
        
                    
             
        
        
        
I don’t think it is a function because you can’t have two 0’s on the Y axis it doesn’t work
