Best ResponseYou've already chosen the best response.1It's the point where a function is minimal. So there it assumes no smaller value. This notion can be seen locally, so that in a neighbourhood of that point the function assumes no smaller value, or globally.

Best ResponseYou've already chosen the best response.0so how do you work it out?

Best ResponseYou've already chosen the best response.1If you have a differentiable function in the real numbers, you can find the local minima by finding the points where the derivative is zero. Of course you still have to check them, for example by looking at the second derivative, to make sure they are not saddle points.

Best ResponseYou've already chosen the best response.0but if you cant differentiate??? coz this is for C1 and we only learn to differentiate in C2 then is there another way of finding it ???

Best ResponseYou've already chosen the best response.0well, its state the coodinates of the minimum point on the graph of y7x+6 that is the qs :S is that what you wanted?

Best ResponseYou've already chosen the best response.1Do you mean y = 7x+6 ?

Best ResponseYou've already chosen the best response.0soz its y=x^27x+6 soz i didnt know till you told me

Best ResponseYou've already chosen the best response.1Then you can see it algebraically by the method of completing the quadratic. Do you know that?

Best ResponseYou've already chosen the best response.1I mean, completing the square ^^

Best ResponseYou've already chosen the best response.0thats it??? so whenever i see a qs like this its just completing the square??

Best ResponseYou've already chosen the best response.0thanks wait for the minimum do you always need 2 no.? and is there such thing as a maximum? coz i know there is when differentiation

Best ResponseYou've already chosen the best response.1If the parabola is the other way around there is no minimum and a maximum instead.

Best ResponseYou've already chosen the best response.0ok thanks i still use completing the square to find it right thanks

Best ResponseYou've already chosen the best response.1yes, only you will have a minus sign in front of the square
