So let's say that we have three functions. Let's say f of x over some interval is always less than or equal to g of x over that same interval, which is always less than or equal to h of x over that same interval. So let me depict this graphically. So let's depict it graphically right over here. So that is my y-axis. This is my x-axis. And I'll just depict some interval in the x-axis right over here.
