What is the maximum of the sinusoidal function? Enter your answer in the box. A sinusoidal function that begins at negative nine comma one and increases to negative seven comma five and decreases until reaching a low point of negative five comma one. The graph then increases until it reaches a high point of negative three comma five. The graph then decreases until it reaches a low point of negative one comma one. The graph then increases through zero comma three until it reaches a high point of one comma five. The graph then decreases until it reaches a low point of three comma one. The graph then increases until it reaches a high point of five comma five. The graph then decreases until it reaches a low point of seven comma one
