How to plot a graph that I already have in on paper

My quesetion is that, how can I plot a graph that I already have it on a paper. It was given to me by my proffessor but I do not have its function. I attached a picture of it

x axis should be from 0 to 2021 (every 50 years)

y axis has no specific break down, just a limit somewhere on Y axis

I know how to label and put title but I need to know what function should I give to MATLAB to get that shape (I tried logarithm and square root but it I could not get the exact shape.

I appreciate every body's help in advance

Yuo can use this,

to extract the points on the curve, which you can then plot.
