(5/100 600) (12/1000 , -600) 14. Part of a graph of a sinusoidal function f is sketched above. Thc locations of adjacent. maximum and minimum points are shown on thc graph. Use this information to complete thc following (a) what, is the amplitudc of thc sinusoidal function f? (b) what, is the period of thc sinusoidal function f? (c) find an equation which matches the graph, in thc format, y 15. For thc function simplify the differencc quotient h -C))
