Which quadratic equation models the situation correctly
This creates an equation that is a polynomial trig function. With these types of functions, we use algebraic techniques like factoring, the quadratic formula, and trigonometric identities to break the equation down to equations that are easier to work with. As a reminder, here are the trigonometric identities that we have learned so far:r(t) = 132t + 608 Since the revenue obtained from digital music album downloads in the United States increased by approximately 132 million dollars per yer, we have a constant rate of change, and thus can find a linear function to model the situation.
