hat is the minimum of the sinusoidal function? Enter your answer in the box. A sinusoidal function that begins at negative ten comma zero and decreases until reaching a low point of negative nine comma negative four. The graph then increases through negative eight comma zero until it reaches a high point of negative seven comma four. The graph then decreases through negative six comma zero until it reaches a low point of negative five comma negative four. The graph then increases through negative four comma zero until it reaches a high point of negative three comma four. The graph then decreases through negative two comma zero until it reaches a low point of negative one comma negative four. The graph then increases through zero comma zero until it reaches a high point of one comma four. The graph then decreases through two comma zero until it reaches a low point of three comma negative four. The graph then increases through four comma zero until it reaches a high point of five comma four. The graph then decreases through six comma zero until it reaches a low point of seven comma negative four. The graph then increases through eight comma
