I am working on a problem that I don't understand what they want

The curve above is the graph of a sinusoidal function. It goes through the point

and

. Find a sinusoidal function that matches the given graph. If needed, you can enter

=3.1416... as 'pi' in your answer, otherwise use at least 3 decimal digits.

I don't understand what they want

They want a function whose graph matches the picture.

You need to understand amplitude, period, phase (horizontal) shift, and vertical shift.

Have you yet learned about these concepts?
