5 23 SolutionAs we can see the total fluctuation along y axi

Solution

As we can see the total fluctuation along y axis is 4 units from 1 to 5.

And time period is 2 units.

Also the middle of curve is shifted 3 units upward.

Also it is negative of sine wave because after 0 the value first decreases and then increases.

Therefore required equation is y(x) = 3 - 2*sin(pi*x)
