find parametric equation for rectangular equation:

y = x^2 - 4x + 7

$$\begin{array}{|lcll|} \hline \text{ y = x^2 - 4x + 7 is a rectangular equation. }\\ \text{Find a set of parametric equations for the equation } y = x^2 - 4x + 7 \\\\ \text{Solution }: \\ \text{Assign any one of the variable equal to t . (say x = t ). } \\ \text{Then, the given equation can be rewritten as y=t^2 - 4t +7 .}\\ \text{Therefore, a set of parametric equations is x = t and y=t^2 - 4t +7. }\\ \hline \end{array}$$

y = x^2 - 4x + 7

OR

y=(x-2)^2-4+7

y=(x-2)^2+3

x=t+2

y=t^2+3
