Answer 2

Sorry math is not my best subject

Answer 3

What do you think? @undeadknight26

Answer 4

Maximum possible value of \(\cos\theta\) is 1, right?

Answer 5

Can you tell me what the max values of each function are?

Answer 6

Oh mai i forgot to say what i think /.\
Mighty embarrassing....
I thought it was f(x)!
Since its maximum y value was (0,7)

Answer 7

Yes maximum of f(x) is 7

Answer 8

Looks like math to me.

Answer 9

It is math lol...

Answer 10

Can you tell me the maximum of g(x) and h(x)?

Answer 11

Yep, max value of f(x) is 7 :-)

Answer 12

For me f(x) = 7 g(x) = 3 h(x) = -2. I just want to know if i am right with this...

Answer 13

You are correct.

Answer 14

Therefore answer is f(x)

Answer 15

Yosh thanks guys! Care to check like 4 more?

Answer 16

Sure

Answer 17

I think this one is f(x) again

Answer 18

Yep

Answer 19

f(x) = 5
g(x) = 2
h(x) = 1

Answer 20

Actually h(x) is -2

Answer 21

y-intercept is when x=0, right? so just plug in x=0 then solve for y.

Answer 22

\[3\sin(2(0) + \pi )-2 = 3\sin(\pi)-2 = 3(0)-2 = \boxed{-2}\]

Answer 23

Oh yosh that makes sense :O

Answer 24

I think its D

Answer 25

I think this one is C

Answer 26

I think this one is A

Answer 27

All correct.
