To graph an implicit function with boundaries in GeoGebra, you use the ImplicitCurve command, first setting the equation in the standard form f(x, y) = 0. Then, to define the boundaries, use the conditional operator commands for each implicit function variable specifying the desired range of x or y values.
For example.
fx(x) = If(x ≥ ax ∧ x ≤ bx, x, ∞); fy(x) = If(x ≥ ay ∧ x ≤ by, x, ∞)
ax, bx, ay, by -selected variable boundaries.
x²+y²=9 →fx(x)² +fy(x)² =9
