Answer 2

@Vocaloid

Answer 3

@hero if you're not too busy would you mind taking a look at this? I have work to do

Answer 4

What? I've got work to do as well

Answer 5

Oh. sorry :/

Answer 6

alright I have some spare time now

1. just identify where the graph is increasing, is concave down (hint: the graph starts off concave up then at a certain point, the inflection point, changes to being concave down

Answer 7

2. to find the critical points, take the derivative of that function and set it equal to 0. solving for x will give you your critical points

Answer 8

3. same logic for critical points

b) for relative extrema, find where the derivative is equal to 0

c) for inflection points, find where the second derivative is equal to 0

Answer 9

4. uh I think you might want to graph this one and just see where the absolute extrema are
6. take the derivative of both sides wrt t and solve for dx/dt after plugging everything else in

Answer 10

I think(?) for 9 you should apply L'hopital's
8. ehh I honestly forgot, I'd have to re-teach myself this later
10. just look up the definition of L'hope's and re-state in your own words

Answer 11

1
It increases from -1 to 1 then from 1-3 unless it’s looking for increasing up the y axis then from 1-3

Answer 12

Hey I figured out some but I need help still
