The innertube moves up and down in a way such that the height h of the innertube, in meters, above the floor of the pool can be modeled by the function h = asinbx + 3. When the wave pool is turned on, the innertube's height fluctuates between 2 meters and 4 meters, with an interval of 8 seconds between maximums. Based on the context of the problem, what are the values of a and b? O a = 1 and b = = K O a= 1 and b= O a = 2 and b = = O a = 2 and b= Question 3(Multiple Choice Worth 2 points) 05.07 MC) Which of the following functions has an amplitude of 4 and a phase shift of =?
