Best ResponseYou've already chosen the best response.0hard to keep them straight. is this an on line course?

Best ResponseYou've already chosen the best response.0your original function, if i recall, is increasing and then decreasing. changes direction at 0. so one thing you know is that your derivative must be positive to the left of 0 and negative after. let me review them and see if that eliminates any

Best ResponseYou've already chosen the best response.0it eliminate the first one because that parabola is alway positive, aka above the x axis. cross it out

Best ResponseYou've already chosen the best response.0second one is positive and then negative, but it is not correct because it is large far to the left of zero and then gets smaller. but your original function is increasing slowly then increasing rapidly, so your derivative should be a small positive number and then a larger one. cross out #2

Best ResponseYou've already chosen the best response.0what do you mean by it gets smaller after zero?

Best ResponseYou've already chosen the best response.0#3 looks good because where your original function is increasing slowly this one is close to zero but positive. then where your function is increasing more rapidly this one is bigger. then it drops quickly to zero

Best ResponseYou've already chosen the best response.0for #2 i am only looking to the left of the y axis.

Best ResponseYou've already chosen the best response.0your original function is increasing there so your derivative has to be positive.

Best ResponseYou've already chosen the best response.0but your original function is increasing first slowly and then more rapidly

Best ResponseYou've already chosen the best response.0the derivative gives the slope of the tangent lines. if you look at your original function you will see that the slope of the tangent lines is small, that is close to zero, as you start out. then they get steeper so your derivative should get bigger.

Best ResponseYou've already chosen the best response.0#3 you will see that this does just that. it starts out close to zero but then gets larger. this reflects the fact that your original function is increasing slowly and then gets steeper

Best ResponseYou've already chosen the best response.0on the right hand side of the y axis your function is at first decreasing very rapidly, then still deceasing but more slowly. # 3 reflects that as that as soon at is crosses the y axis it drops steeply.
