we were given a function of y=(x-a)(x-b)(x-c) and were told to add in our own numbers i chose y=(x-8)(x+5)(x-3). can some one show me the working to get it to a cubic and then the derivative
lets say it was (x - 8)(x + 5), could you expand that?
expand the first two first, and then multiply what you got by the (x - 3). how? first multiply everything by the x and then multiply everything by the -3
when finding the derivative, all that is needed is the power rule:
and of course, if there are constants in front of the x's, you just leave them and multiply what you got by them since . here, your is
(why did you choose such big numbers? )
