Question

What is a possible formula for the graph attached inside? :)

f(x)=_________

thanks :)

Answer 1

graph :)

Answer 2

Notice it's shifted up 3,

and the period is 6

and the amplitude is 3

Follow the last question, see if you can work out the formula.

Answer 3

okay... umm

f(x)=AsinBt+C ?

so f(x)=-3sin+(2pi/6) + 3 ?

and simplifies to f(x) = -3sin + 1/3pi + 3 ? :/

Answer 4

i think i forgot something...

should it be 1/3pi x ?

or t? :/

Answer 5

Amplitude is just 3 this time.

B = 2pi/T where T is period

And it's sinBt not sin+Bt :P

Answer 6

oh oops!

and there's no +C here is there?

Answer 7

so f(x)=AsinBt ?

Answer 8

Follow the last question haha :P C is the shift up

Answer 9

right :P

okay

so f(x)=AsinBt+C

f(x)=3sin(2π/6) + 3

f(x)=3sin(π/3) + 3 ?

Answer 10

You're still missing t...

Answer 11

ohh :(

f(x)=3sin(pi/3)t+3 ?

Answer 12

Good :)

Answer 13

yay!! :) thanks!! :)

Answer 14

good job :)

Answer 15

hehe thank you!! :) i seriously need to remember the t though lol.. i keep forgetting it :P

Answer 16

haha yes :) can't forget the variable
