# How do you evaluate the function #p(x)=x^2-2# for #p(-2)#?

To evaluate the function ( p(x) = x^2 - 2 ) for ( p(-2) ), substitute ( x = -2 ) into the function:

[ p(-2) = (-2)^2 - 2 ]

[ p(-2) = 4 - 2 ]

[ p(-2) = 2 ]

So, ( p(-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.
