Chloe AlexanderTo find ( f(-x) ), you simply replace every occurrence of ( x ) in the function ( f(x) ) with ( -x ). So, for the function ( f(x) = x^2 - x ), we have:
[ f(-x) = (-x)^2 - (-x) ] [ = x^2 + x ]
Therefore, ( f(-x) = x^2 + x ).

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.
