-- 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 .

The value of k is 400 points.

If the player fails to complete 100 tasks, then they lost 200 points. At the end of the game, they had 200 points.

We can write and solve the following equation to determine where they started.

x - 200 = 200
x = 400
