Identify the sine function with the given attributes.
amplitude: 1; period: 2; phase shift: 3; vertical shift: 4

Last option

Step-by-step explanation:

The general sine function has the following form  

Where A is the amplitude: half the vertical distance between the highest peak and the lowest peak of the wave.  

is the period: time it takes the wave to complete a cycle.

k is the vertical displacement.

phase shift

We know that:

amplitude: 1; period: 2; phase shift: 3; vertical shift: 4

Thus:

Then the function is:

The answer is last option

i could probably can you me with a question of mine?
