Does anyone know how to find the first and second derivative of:
w=3x⁷-7x³+21x²

Yes, quite a few of us know what these derivatives are. But I suspect that you're the one who needs to know what they are, right?

You started by applying the Power Rule they gave you for derivatives, and... then what? Where are you stuck?

Please be complete. Thank you!
