What is the smallest positive integer for x so that f(x)=200(2)* is greater than the value of g(x)=500x+400?

We have to functions, namely:



So the problem is asking for the smallest positive integer for so that is greater than the value of , that is:



Let's solve this problem by using the trial and error method:



So starting from 1 and increasing it in steps of one we find that:



when

That is, the smallest positive integer for so that the function is greater than is 4.
