2. In a study on the speed of muscle contractions in frogs under various loads it has been found that the 26+0.06x X speed decreases with increasing loads. The relationship has been found to be V(x)=- where is the speed of the contraction in cm/sec and x is the load in grams. a) What does V approach as x increases? b) Sketch a graph of the function. c) What is the value of x when V =3 cm/sec? Answers: 2a) 0.06 cm/sec c) 8.8 grams
