Small utility that takes in a formula as function f(x) and draws a graph based on it

This is a small utility that takes a formula of f(x) function from a textbox, calculates points in background using VBS, and draws a graph based on this function in a PictureBox control, with gridline and coordinate system. The utility also enables the user to zoom in and out of the graph, to move it around, and also can show specific points of the curve using the mouse.

I acquired Masters degree in computing science at the Faculty of Electrical Engineering and Computing in Zagreb, Croatia in 2009. Following my studies, I got a job in a Croatian branch of Austrian-based CEE Raiffeisen Bank as an MIS (Management information system) analyst.
I have been working there since 2010, as an IT expert within the Controlling department, maintaining the Oracle's OFSA system, underlying interfaces and databases.
Throughout that time, I have worked with several different technologies, which include SQL & PL/SQL (mostly), postgres, Cognos BI, Apparo, Datastage, ODI, Jenkins, Qlik, ...
I am doing a lot of automation with scripting in batch / shell and VBscript (mostly) - data analysis and processing, automated DB imports and exports, Jenkins automation etc.
Privately, I was mostly doing Windows Forms and Console app tools in Visual Studio, C#.
