Please show all work. Show detailed work. Do not skip any algebra steps. Show everything. All work and answers must be clear and legible. Please do not write in cursive. All calculus rules used must be clearly labled with the name of any rule used and marked where it is used in your work. Please answer all sub-parts, per answers policy. Please circle or box your final answer. If all work is clearly shown, answers are correct, and everything is legible, I will give thumbs up. If not, it will be thumbs down. Thank you for what you do.
