How to parametrize a function ?

So i have function like y^(0.5) = x this function created by syms command and id like to replace x with t and find y in terms of t. then r =[x,y] disp(r)

[John D'Errico]

syms x y
eq = sqrt(y) == x;
syms t real
ysol = solve(subs(eq,x,t),y,'returnconditions',true)

ysol = struct with fields:
             y: t^2
    parameters: [1×0 sym]
    conditions: 0 <= t

The constraint tells you that t must be positive. This is because the original equation was written as sqrt(y), which presumes the positive branch of the square root function.

And sir its not leaving alone y when y has a power for example x^3 == y^2
