Question

Will award a metal
Which function has the smallest minimum y-value?
I think it is f(x)

Answer 1

@VeritasVosLiberabit @Hero

Answer 2

Is f(x) correct?

Answer 3

not f(x)

Answer 4

g(x)

Answer 5

This problem is similar to the last one. g(x) is easy to see the smallest value is -3

Answer 6

Are you just guessing @gamer456148. Tell me why g(x)

Answer 7

Well h(x) is a parabola

Answer 8

Failed the test, oh well

Answer 9

ok nice observation, but that won't be enough to say whether that one has the smallest minimum

Answer 10

How did you get so good at mathematics?

Answer 11

You need to look at each equation and look at its individual properties to see what is the smallest possible value it can have. ideally the smallest value a function can have is \[-\infty\]. these equations cannot

Answer 12

@gamer456148 I'm old and in college hehe

Answer 13

You're good at math too. Just keep practicing and understanding as much as you can.

Answer 14

Well I have to redo this exam and 40 more that are overdue and it is tiring me out because I can't understand it. If I had that many late tests in college I would get kicked out

Answer 15

ah I understand. Just don't get overwhelmed. Taking a small break can sometimes do wonders. I also like to just watch a video like khanacademy if I get too tired of doing problems.

Answer 16

Let me see if I can type a good explanation up for this one for you

Answer 17

Shannon's scooter has a piece of tape stuck to the tire. If the tire has a diameter of 18 inches, how far does the piece of tape travel in 72° of rotation?

Answer 18

18pi/5

Answer 19

Hey @gamer456148 I messed you up you were right

Answer 20

f(x) does have the smallest minimum.

Answer 21

Damn it, lol

Answer 22

I forgot that sin(x) can be -1

Answer 23

did you have to submit something?

Answer 24

Yes

Answer 25

aww man, very sorry about that

Answer 26

Maybe I should take a break :P

Answer 27

yeah f(x) can be -5 when sin(x)=-1

Answer 28

can you e-mail your teacher the mistake and correction?

Answer 29

Its fine, just take a break, and no I can't

Answer 30

I'll take a look at your other one in the meantime

Answer 31

oh the scooter one has to do with the arc length equation

Answer 32

\[s=r \theta \] where s is the arc length or distance the tape has travelled

Answer 33

18pi/5 is what I think is the answer

Answer 34

I'm getting almost that but times 2

Answer 35

\[s=72\frac{ \pi }{ 180 }18\]

Answer 36

\[\frac{ 2\pi }{ 5 }18\]

Answer 37

Not one of the choices

Answer 38

can you post the answers and I'll take a look.

Answer 39

oh whoops 18 is the diameter

Answer 40

so yeah your answer is right

Answer 41

\[s=\frac{ 18\pi }{ 5 }\]

Answer 42

That is what I said

Answer 43

Though this isnt the same problem, imma just post it here:
