Question

Choose the function whose graph is given by:O A. y= sin(x + 2)B. y = cos(x - 1)O C. y= sin(x-2)O D. y = sinx-2

Answer 1

The graph below is a wave that cuts the y-axis at a point close to -1.

So our answer should be between

`\begin{gathered} y=cos(x-1)\text{ or} \\ y=sin(x-2) \end{gathered}`

But the cosine graph would cut the y-axis at a positive y-value, while the sine graph does that at a negative y-value.

Hence the answer is

`y=sin(x-2)`

Hence the answer is option C
