You just got your derivatives test back, and you can’t under- stand why that teacher of yours deducted so many points for what you thought was your best work: f ' ( a ) = lim h → 0 f ( x + h ) − f ( x ) h = lim h → 0 f ( x ) + h − f ( x ) h = lim h → 0 h h Canceled the f ( x ) = 1. X WRONG − 10 What was wrong with your answer? (There may be more than one error.)
