Transcript

00:00

Thank you We sneak And here's your smoke too Sure

00:06

brought to you by clown fish along with sea lions

00:09

and tiger sharks they're always a big draw An underwater

00:12

circus that all right check out this info Scientists about

00:17

the clown features are home their toxicity and enemies being

00:19

the most talked about me All right Which of the

00:24

following graphs best models the relationship between a gn enemy

00:28

toxicity x and the number of clown fish Why And

00:33

here the pencil answer All right who doesn't choose their

00:38

home based on the an enemy toxicity Back when our

00:41

realtor was helping us get a new pad that was

00:44

one of the main things we looked for A quiet

00:46

neighborhood good schools and good and enemy toxicity Hey it

00:49

wasn't our first rodeo All right This one is simple

00:53

enough information wise when the an enemy had a toxicity

00:56

of one or nine In other words on the very

00:58

high end or the very low in the clown fish

01:01

population wasn't very high at toxicity levels of three and

01:06

seven So a little bit higher than the lowest lows

01:09

and a little bit lower than the highest of highs

01:11

A few more clownfish had set up shop but a

01:15

toxicity level of five smack dab in the middle It

01:18

was an absolute clown Fish haven apparently that's their hamptons

01:23

The question is which of these four graphs best represents

01:27

this relationship of clownfish to a gn enemy toxicity Well

01:32

since five is the prime toxicity level and the clown

01:35

fish population falls on either side of that number That's

01:39

going to need to be the vertex of our cur

01:42

Since the clown fish population drops off the further below

01:46

or above that number we go The graph should also

01:49

drop off on both sides from that point Well graft

01:53

b doesn't have the right vertex that uses the point

01:55

three too So we can rule that one out right

01:57

away and graphs See the vertex of five is a

02:00

minimum not a maximum indicating that this is where you

02:03

find the fewest clown fish with no for a fact

02:06

is other hug walk He was apparently blindfolded and turned

02:10

around a few times because well it's totally disoriented there's

02:13

No maximum representative x equals five So we can nix

02:16

thea's Well well the award for graph of our dreams

02:19

goes the option a which has a vertex of the

02:22

appropriate spot and demonstrates that the clown fish population decreases

02:27

the further away you get from that number So if

02:29

you're ever passing through a potential clownfish neighborhood and you

02:32

don't particularly care for the cut of their jib well 00:02:35.83 --> [endTime] you know where to hang Out
