how should i write the mathematical expression according to this

 

when 2 graphes are located above the x axix ,find for what x values the graph of f(x) function  is located above the graph of g(x) function ?should i wrute it this way:

 

g(x)>0 and  f(x)>g(x)

 

note that in previous paragraph i found when the graph of g(x) is above x axix and when f(x) is above the graph of g(x) function

We just want to write  f(x) - g(x) > 0    ....in other words, we want all the values such that the height of the graph of f(x) at some value of x is greater than the height of the the graph of g(x) at the same x value

Yes I will go for that

g(x)>0,    f(x)>0   and     f(x)-g(x)>0
