Please zoom in and help me solve these. I need it for my study guide. I really appreciate your help :)

#3 The graph of a sinusoidal function is shown. Describe this graph by determining its Equations of Sinusoidal Functions #1 y = a - sin (bx + c) +d a represents: b represents: ONA represents: Equation of its midline: 120 240 360'480'600 720" d represents: N - Amplitude: #2 The height of a swing over time can be modelled by the function. Treat this equation just like you would a sin function. h(1) =15 cost - Period: where h is the height in centimetres above the ground and t is the time in seconds, a. What is the highest point the swing will reach? #4 The graph of a sinusoidal function is shown. Describe this graph by determining its: b. Determine the height of the swing at 3.5 s and at 8.0 s. c. In terms of the movement of the swing, explain what the 65 represents. The equation of its midline: o - d. Explain what the 15 represents in terms of the movement of the swing 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 -2 - Amplitude: Period
