From the graph we can see that the parabola is a smiling parabola,
meaning that its extreme point is a minimum point.
If we describe it in words, until the extreme point the function decreases,
after the extreme point it increases.
Since we measure the progress using X,
we can say that the function increases whenever X is greater than point C, the extreme point.
Mathematically we can write:
X>C
As we already said, as long as X is greater than C, the function increases.
x > C
