This is a pre-calc question. I don't understand how to solve the question. Can someone please help me?
I hope I'm understanding this question properly.
sine(a) can be at most 1, and at least -1.
To get the lowest temperature, we want sine(a) to be the highest number.
That means sine(7x/3 + 1/6) = -1.
-19 * 1 -3 = -22
To get the highest temperature, we want sine(a) to be the lowest number, -1.
-19 * -1 - 3 = 16
I hope that was helpful.
