The temperature of a chemical reaction ranges between 40°C and 180°C. The temperature is at its lowest point when t = 0, the temperature is 90 degrees and increasing. What is a sine function that would model this reaction?

f(x) = 70 sin 12x + 110

f(x) = 110 sin 12x + 70

f(x) = 70 sin pi over 6x + 110

f(x) = 110 sin pi over 6x + 70

are you sure you have the right answer choices @mathfinder2014 if you plug x=0 you never get 90 only 70 or 110
