If x=[0:5:1000] and F(x)=[0:0.25:50], which one of these plots represents the relationship between x and F(x)?

So all the graphs have the same range being f(x) on the Y plane going from 0 to 50, and Log(x) on the X plane going from 10^1 to 10^3. The difference between the sloped lines is how high they go on the Y plane. The first option going to 20, the second going to 30, the third going to 40, and the fourth going to 50.
