Question

Which of the following equations matches the function shown above?

Answer 1

So, the function is obviously shifted up by 1 so it rules out A and B, and we also see that the period is 4pi rather than 2pi, and using the fact that:

`(2\pi)/(b)=4\pi \implies (b)/(2\pi)=(1)/(4\pi)\implies b=(1)/(2)`

Now that we know our b value, we see that the correct answer would be C.
