Given the parametric equations: x=t - 1/t, y=t + 1/t

Find the intervals where the curve is increasing and decreasing. State intervals in interval location.
Find intervals of concavity for the parameter where the curve is concave up and concave down. State intervals in interval location.

Hey I just met ya
This is crazy

But here's my number

So call me maybe

It's hard to look right

At you, baby

But here's my number

so call me maybe

Hey, I just met you

and this is crazy

But here's my number

So call me maybe

And all the other boys

Try to chase me

But here's my number

So call me maybe

You took your time with the call

I took no time with the fall

You gave me nothing at all

But still, you're in my way
