Hints
1. This signal starts at zero and moves like the Ocean
2. This signal is never less than 0, but is always less than 4.
3. This signals period and the price of a footlong subway sandwich have the same value.
Answer
Part 1 makes is implying a sine wave.
Part 2 is telling us that the amplitude is 2 and the offset is 2.
Part3 tells us that the period is 5, making $ \omega=\frac{2\pi}{5} $
Thus this signal is....
$ x(t)=2sin(\frac{2\pi}{5}t)+2 $
