Given the function #k# described by #k(x)=x+18#, how do you find #k(-15)#?
Nathan AxelTo find ( k(-15) ), substitute (-15) for ( x ) in the function ( k(x) = x + 18 ). So, ( k(-15) = -15 + 18 = 3 ). Therefore, ( k(-15) = 3 ).

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.
