Hey, Christian, how are you?
You can do
f[a_Integer,x_Real]:=a*x^2
so, when you use manipulate, you will be able to run the following code
Manipulate[Plot[f[a,x],{x,-5,5}],{a,1,50,1}]
Hello Estevao,
thank you so much for helping!
Im not sure but naybe you could use some assumptions. https://reference.wolfram.com/language/guide/AssumptionsAndDomains.html

Thank you so much for your reply! It works perfectly, however, do you also have a solution where I can define the parameter globally? In a way, that I can define a as an integer and use this to define several functions? Or do I have to enter every time I use the parameter that this is an integer?
Thank you so much!
