$y = x -2, x\geq 1$

Step-by-step explanation:

In the question given correct parameter is - 2) $y = x -2, x\geq 1$

Method -

$x= t^2 + 1$ ........................(1)

$y = t^2 - 1$ ..........................(2)

Let's solve the equation 1,

⇒ $x = t^2 +1$

⇒ $t^2 = x - 1$

Put the value of t² in equation 2

$y =t^2 - 1 \\y = x -1 -1\\y = x - 2$

Here we got the y parameter as $y = x -2$

So the option no .2 is the correct option 2) $y = x -2, x\geq 1$
