Eliminate the parameter in the equations y is equal to t plus 2 and x is equal to t raised to the 1 half power How can the rectangular equation be described?

From x = √t, square both sides to get t = x² (with x ≥ 0). Substitute this into y = t + 2 to obtain the rectangular equation y = x² + 2, which is quadratic. Therefore, the equation is described as quadratic.
