Which function describes the graph in the picture? NEED HELP ASAP

Answers

-- The function is a sine or cosine that wiggles from 3 below to 3 above its average value. So the amplitude is 3 . That lets out the 1st and 3rd choices.
It has to be the 2nd or 4th choice.

Looking at the graph, the y-intercept is at y=6.
The y-intercept is the point where x=0, so f(0)=6.

Test the 2nd choice: f(x) = 3 cos(x) + 3

   f(0) = 3 cos(0) + 3

cos(0) = 1 so f(0) = 3 (1) + 3    = 6

Choice-2 is looking good.
Just to be sure, let's check choice-4:

   f(x) = 3 sin(x) + 3

   f(0) = 3 sin(0) + 3

sin(0) = 0 so    f(0) = 3 (0) + 3    = 3

Beautiful ! Choice-4 flopped. The answer is choice-2 .

Transformati in metri: 4 dam. 5hm 2475cm. 14 573mm.0,0124

Answers

1 dam = 10 mt
1 hm = 100 mt
1 cm = 0,01 mt
1 mm = 0,001

*4 dam
4*10 = 40mt

*5 HM
5*100 = 500mt

*2475 cm
2475*0.01 = 247.500 mt

* 14 573mm
14573 * 0.001 = 14.573
