Differentiation

What grade are you aiming for?

I aspire for an A but only 3 weeks to get that.

I believe you can do it but you're going to have to continue to work as hard as you've been doing over the last few days.

If you're doing the higher paper then your teacher should have taught you every topic in the higher course. It's weird that this hasn't happened.

But it's great that you're aiming for better than the rest of your class!

A curve has equation y = 2x³ + x² - 8x + 3.
Hi

Can someone please guide me through answering the above question step by step?

Thanks.

Hi class is very disruptive too so not enough time to even cover all content. Most people don't care. I have printed 4 papers for my exam and I have a practise book too with loads of questions for each topic... :-)

BTW I'm working at a C atm. Do you still believe I can do it and thanks very much! Well I've been at a C since the start of the year! Started studying loads now.

From the evidence of this thread, you're working much harder than the average C level student.

If you continue to work as hard as you ever have then you've got a chance.
