Chapter 9 - Section 9.5 - Parametric Equations - Exercise Set - Page 1020: 56


The different sets of parametric equation are: $ x=t,\,y={{t}^{2}}-3\,\text{ and }\,x={{t}^{2}},\,y={{t}^{4}}-3$ (other answers are possible.)

Work Step by Step

Let us assume, $ x=\,t $, then $ y={{t}^{2}}-3$ After that, $ x=\,{{t}^{2}}$, then $ y={{t}^{4}}-3$ Thus, $ x=\,t $, $ y={{t}^{2}}-3$ and $ x=\,{{t}^{2}}$, $ y={{t}^{4}}-3$ are two different sets of parametric equations.
