    Sine Graph

    Could someone please explain to me how to do this question? I am confused on how to find the equation. I think the s. axis is 4.5? and amputude is 3.5? so y=3.5sin( ) ( ) + 4.5 but where do I go from there?......

    you need to look at the scale on the vertical axis again ... every block is 1 m

    amplitude is 4

    period is 8

    vertical shift is 5

    y = 4\sin\left(\frac{\pi}{4} t\right) + 5
