sir, but three variables means three dimension right?

[@PrimeNewtons]

x = 5 is one dimension f(x)= 5 x is 2 dimensions f(x,y) = x² + y is 3 dimensions f(x,y,z) = x + y+z is 4 dimension f is also a variable. The dependent variable. Plus, they all partially depend on one another.

[@bravo2992]

I get it now sir! Thank you so much for answering me :)@@PrimeNewtons

[@harshplayz31882]

I will try this function in python😂

[@Per0xide-ik5do]

How'd it goo 😂😂

Thanks alot

[@pedrogarcia8706]

could you also write the Range of the second function as "z ∈ R"?
