To find the velocity as a function of time ( t ), you need to differentiate the equation ( y = \frac{1}{t + 2} ) with respect to ( t ). The derivative of ( y ) with respect to ( t ) will give you the velocity function ( v(t) ). So, you differentiate ( y ) with respect to ( t ) using the quotient rule:

[ \frac{dy}{dt} = -\frac{1}{{(t + 2)}^2} ]

So, the velocity function as a function of time ( t ) is ( v(t) = -\frac{1}{{(t + 2)}^2} ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
