At the beginning of the lesson, the radical function S = 15.9VLf was introduced, where S is the speed of the vehicle in km/h, L is the length of the skid marks in metres, and f is the coefficien friction. The coefficient of friction for a particular road made of asphalt pavement is 0.80. The new function would be S = 15.9V0.80L. a. Describe the transformations required to transform the function S = VL into the function S= 15.9V0.80L . (2 marks) Core b. Graph the function S = 15.9V0.80L .
