I´m new to App Designer and not really sure where to start, with creating the code for each Radio Button.

Steps: (Or Refer any tutorial, please check in the MATLAB youtube channel)
1. Open MATLAB
2. Type the following in the command window
>> appdesigner
2. Just drag and drop all required blocks, chahe the texts as per requirements
4. Call Back activate (Right Click on the Radio Button Group)
5. Insert the following code, its just the if else condition
6. Run the code
SteselectedButton = app.yButtonGroup.SelectedObject;
x=1:0.05:100;
if app.sinxButton.Value
y=sin(x);
plot(app.UIAxes,x,y);
title(app.UIAxes,'y=sin(x)');
elseif app.cosxButton.Value
y=cos(x);
plot(app.UIAxes,x,y);
title(app.UIAxes,'y=cos(x)');
elseif app.xButton.Value
y=2*x;
plot(app.UIAxes,x,y);
title(app.UIAxes,'y=2x');
elseif app.lnxButton.Value
y=log(x);
plot(app.UIAxes,x,y);
title(app.UIAxes,'y=ln(x)');
else
y=exp(x);
plot(app.UIAxes,x,y);
title(app.UIAxes,'y=e^x');
end
