Making a Linear, Parabolic, and Logarithmic Trend line

I'm stuck on which code should I use on making a trend line on my project using App Designer. I search everywhere but I didn't get the result I needed.

Here is the code on my App Designer

classdef Enhaynes_FinalExam < matlab.apps.AppBase

            if nargout == 0
                clear app

        % Code that executes before app deletion
        function delete(app)

            % Delete UIFigure when app is deleted
            delete(app.UIFigure)
        end
    end
end

is there a way that I can show a trend line and which code I should use?

I would use fit to do this. You can choose the type of fit you want.
