(1 point) A population of animals oscillates sinusoidally between a low of 200 on January 1 and a high of 1200 on July 1. Graph the population against time and use your graph to find a formula for the population P as a function of time t, in months since the start of the year. Assume that the period of P is one year. P(t) = C] (1 point) Find the formula for the graph of the function f (x) given in the graph above. f(x) =0 (1 point) -2pi Find a formula for the graph of the function y = f(x) given in the figure above. y =
