Question

From a statistical model, the prices of apples and strawberries are expected to be given by the functions p1(t) = 3.2 + 2t − 0.2t2 and p2(t) = 3.8 + t − 0.1t2, respectively, where t is the month. What will be the difference in the prices of apples and strawberries in month 6? 2.8 1.8 2.1 1.1 3.1

Answer 1

So this is really simple. Just plug both equations into your y= button and evaluate t at 6 for both functions. Then just subtract one function from the other, and take the absolute value of your answer. That will get you your difference.
